When waiting indefinitely for a new cluster state in a test,
TestClusterService#add will throw a NullPointerException if the timeout
is null. Instead, TestClusterService#add should guard against a null
timeout and not even attempt to add a notification for the timeout
expiring. Note that the usage of null is the agreed upon contract for
specifying an indefinite wait from ClusterStateObserver.
We used to write into an in-memory buffer and if necessary also allow reading
from the memory buffer if the some translog locations that are not flushed to
the channel need to be read. This commit hides all writing behind a buffered output
stream and if ncecessary flushes all buffered data to the channel for reading. This allows
for several simplifcations like reusing javas build in BufferedOutputStream and removes the
need for read write locks on the translog writer. All thread safety is now achived using
the synchronized primitive.
Several IOExceptions are always wrapped in an NotSerializableWrapper which is
annoying to read. These exceptions are important to get right across the network
and we should support the important ones that indicate problems on the Filesystem.
This commit also adds general support for IOException to preserve the parent type
across the network if no specific type is serializable.
As a default in V2, the GeoPointField.stored option was set to true. Since this consumes disk space with no positive benefit the default stored option is being reverted back to false.
This commit restores logging the ShardRouting#shardId at the front of
the log messages in ShardStateAction. The reason for this is so that
shard-level log messages have the format "[component][node][shard]
message".
There are two bugs:
- the 'global_ordinals_low_cardinality' mode requires a fielddata-based impl so
that it can extract the segment to global ordinal mapping
- the 'global_ordinals_hash' mode abusively casts to the values source to a
fielddata-based impl while it is not needed
Closes#14882
This commit modifies the handling of cluster states in
o.e.c.a.s.ShardStateAction so that all necessary state is obtained
externally to the ShardStateAction#shardFailed and
ShardStateAction#shardStarted methods. This refactoring permits the
removal of the ClusterService field from ShardStateAction.
This commit applies a minor code cleanup to
o/e/c/ClusterStateObserver.java. In particular
- employ the diamond operator instead of explicitly specifying a
generic type parameter
- use 'L' instead of 'l' for specifying a long literal
- remove redundant static modifier on a nested interface
- remove redundant public access modifiers on interface methods
- reformat the declaration of the four-argument ChangePredicate#apply
- simplify the bodies of ValidationPredicate#apply
This commit fixes multiField support for GeoPointFieldMapper by passing an externalValueContext to the multiField parser. Unit testing is added for multi field coverage.
The MapperService doesn't currently check the
index.mapper.dynamic setting during index creation,
so indices can be created with dynamic mappings even
if this setting is false. Add a check that throws an
exception in this case. Fixes#15381
