[hbase] TestHStoreFile/TestBloomFilter hang occasionally on hudson AFTER test
has finished
------------------------------------------------------------------------------------------
Key: HADOOP-2040
URL: https://issues.apache.org/jira/browse/HADOOP-2040
Project: Hadoop
Issue Type: Bug
Components: contrib/hbase
Reporter: stack
Priority: Minor
Weird. Last night TestBloomFilter was hung after junit had printed test had
completed without error. Just now, I noticed a hung TestHStore -- again after
junit had printed out test had succeeded (Nigel Daley has reported he's seen at
least two hangs in TestHStoreFile, perhaps in same location).
Last night and just now I was unable to get a thread dump.
Here is log from around this evenings hang:
