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
Add override creating an HFile in tmp that takes a TimeRangeTracker
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.
