HBASE-16176 Bug fixes/improvements on HBASE-15650 Remove
...
TimeRangeTracker as point of contention when many threads reading a StoreFile
Fixes HBASE-16074 ITBLL fails, reports lost big or tiny families broken
scanning because of a side effect of a clean up in HBASE-15650 to make
TimeRange construction consistent exposed a latent issue in
TimeRange#compare. See HBASE-16074 for more detail.
Also change HFile Writer constructor so we pass in the TimeRangeTracker, if one,
on construction rather than set later (the flag and reference were not volatile
so could have made for issues in concurrent case). And make sure the construction
of a TimeRange from a TimeRangeTracer on open of an HFile Reader never makes a
bad minimum value, one that would preclude us reading any values from a file
(set min to 0)
M hbase-common/src/main/java/org/apache/hadoop/hbase/io/TimeRange.java
Call through to next constructor (if minStamp was 0, we'd skip setting
allTime=true). Add asserts that timestamps are not < 0 cos it messes
us up if they are (we already were checking for < 0 on construction but
assert passed in timestamps are not < 0).
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HStore.java
Add constructor override that takes a TimeRangeTracker (set when flushing
but not when compacting)
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/Store.java

M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/StoreFile.java
Add override for HFile Writer that takes a TimeRangeTracker Take it on
construction instead of having it passed by a setter later (flags and
reference set by the setter were not volatile... could have been prob
in concurrent case)
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/TimeRangeTracker.java
Log WARN if bad initial TimeRange value (and then 'fix' it)
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestTimeRangeTracker.java
A few tests to prove serialization works as expected and that we'll get a bad min if not constructed properly.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/ScanQueryMatcher.java
Handle OLDEST_TIMESTAMP explictly. Don't expect TimeRange to do it.
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestQueryMatcher.java
Refactor from junit3 to junit4 and add test for this weird case.

Now implementing the claim queues procedure within an HBase table.
Also added UnitTests to test claimQueue.
Peer tracking will still be performed by ZooKeeper though.
Also modified the queueId tracking procedure so we no longer have to perform scans over the Replication Table.
This does make our queue naming schema slightly different from ReplicationQueuesZKImpl though.

- Testing by executing a command will cover the exact path users will trigger, so its better then directly calling library functions in tests. Changing the tests to use @shell.command(:<command>, args) to execute them like it's a command coming from shell.
Norm change:
Commands should print the output user would like to see, but in the end, should also return the relevant value. This way:
- Tests can use returned value to check that functionality works
- Tests can capture stdout to assert particular kind of output user should see.
- We do not print the return value in interactive mode and keep the output clean. See Shell.command() function.
Bugs found due to this change:
- Uncovered bug in major_compact.rb with this approach. It was calling admin.majorCompact() which doesn't exist but our tests didn't catch it since they directly tested admin.major_compact()
- Enabled TestReplicationShell. If it's bad, flaky infra will take care of it.

...
It added this in AsyncProcess#waitForMaximumCurrentTasks:
synchronized (this.tasksInProgress) {
+ if (tasksInProgress.get() != oldInProgress) break;
this.tasksInProgress.wait(100);
which added a break out of our waiting loop if any change in
count of tasks; it seems that what was wanted was instead to
avoid the wait if there was movement in the count of completed
task.
Reformats waitForMaximumCurrentTasks so it is testable. Adds
test that we indeed wait on the specified parameter.

HBASE-15441 Fix WAL splitting when region has moved multiple times
...
Summary:
Currently WAL splitting is broken when a region has been opened multiple times in recent minutes.
Region open and region close write event markers to the wal. These markers should have the sequence id in them. However it is currently getting 1. That means that if a region has moved multiple times in the last few mins then multiple split log workers will try and create the recovered edits file for sequence id 1. One of the workers will fail and on failing they will delete the recovered edits. Causing all split wal attempts to fail.
We need to:
It appears that the close event with a sequence id of one is coming from region warm up.
This patch fixes that by making sure the close on warm up doesn't happen. Also splitting will ignore any of the events that are already in the logs.
Test Plan: Unit tests pass

HBASE-15232 Handle region location cache mgmt in AsyncProcess for multi()'s
...
Further investigation after HBASE-15221 lead to some findings that
AsyncProcess should have been managing the contents of the region
location cache, appropriately clearing it when necessary (e.g. an
RPC to a server fails because the server doesn't host that region)
For multi() RPCs, the tableName argument is null since there is no
single table that the updates are destined to. This inadvertently
caused the existing region location cache updates to fail on 1.x
branches. AsyncProcess needs to handle when tableName is null
and perform the necessary cache evictions.
As such, much of the new retry logic in HTableMultiplexer is
unnecessary and is removed with this commit. Getters which were
added as a part of testing were left since that are mostly
harmless and should contain no negative impact.

HBASE-15221 Reload the cache on re-tried puts in HTableMultiplexer and adds a close() method to HTableMultiplexer
...
When a Put fails due to a NotServingRegionException, the cached location
of that Region is never cleared. Thus, subsequent calls to resubmit
the Put will fail in the same way as the original, never determining
the new location of the Region.
If the Connection is not closed by the user before the Multiplexer
is discarded, it will leak resources and could cause resource
issues.

HBASE-14669 remove unused import and fix javadoc
2015-10-22 09:25:26 -07:00
2996355e94
HBASE-14603 Lots of work on the POM to enhance Javadocs, Xrefs
...
* We now have apidocs, devapidocs, testapidocs, and testdevapidocs
* When using reportSets, the Javadoc plugin ignores the plugin configuration,
so I propagated it to the individual reportSet configuration blocks.
* I was able to remove some of the logic that moved / copied things around
in post-site.
* We now have xref and xref-test (these are superfluous but something needs them
so I left them)
* Added source to Javadocs -- you can click a method or property to browse its source.
More user-friendly than xref maybe.
* You can now get the whole site to build by doing 'mvn clean site site:stage' and
it takes about 10 minutes.
