---------------------------------------
Summary: HBase metastore causes massive number of ZK exceptions in
MiniTez tests
Key: HIVE-12167
URL: https://issues.apache.org/jira/browse/HIVE-12167
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Assignee: Daniel Dai
I ran some random test (vectorization_10) with HBase metastore, and I see large
number of exceptions in hive.log
{noformat}
$ grep -c "ConnectionLoss" hive.log
52
$ grep -c "Connection refused" hive.log
1014
{noformat}
These log lines' count has increased by ~33% since merging llap branch, but it
is still high before that (39/~700) for the same test). These lines are not
present if I disable HBase metastore.
The exceptions are:
