Anoop Sam John commented on HBASE-10451:
----------------------------------------
TestEncodedSeekers -> Locally it is passing (with out any hang) many times.
Though I observed significant delay in run. The test creates some 100000+ Gets.
For every get we create Scan and open Scanner for HFiles. Each of this
creates a LRUDictionary with size as Short.MAX_VALUE and LRUDictionary eagerly
creates those many Node objects. This kill us in the tests.
HBASE-10585 can solve this issue upto great extend.
Still I feel LRUDictionary size of Short.MAX_VALUE is too much for the Tag
dict. This can be Byte.MAX_VALUE IMO. With these changes, the tests become
much much faster. Once I commit HBASE-10585, will post the new patch here so
as to get a QA run.
With the new patch the IntegrationTestIngestWithVisibilityLabels passing in
cluster. One more thing is Integration tests creates the test tables using LTT
-init_only option. LTT allows to pass DBE etc to be used for the tables though
the IntegrationTestIngest don't allow. For the above test I just patched
IntegrationTestIngest so as to make the table with FAST_DIFF DBE. Will open
a new Jira so as to support passing table create options for the Integration
tests.
