Ted Yu created HBASE-9651:
-----------------------------
Summary: Backport HBASE-3890 'Scheduled tasks in distributed log
splitting not in sync with ZK' to 0.94
Key: HBASE-9651
URL: https://issues.apache.org/jira/browse/HBASE-9651
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Assignee: Ted Yu
Fix For: 0.94.13
Attachments: 9651.patch
HBASE-3890 was fixed in 0.96 and trunk. This issue is to backport to 0.94
Note that there must be more slightly off here. Although the splitlogs znode is
now empty the master is still stuck here:
{code}
Doing distributed log split in
hdfs://localhost:8020/hbase/.logs/10.0.0.65,60020,1305406356765
- Waiting for distributed tasks to finish. scheduled=2 done=1 error=0 4380s
Master startup
- Splitting logs after master startup 4388s
{code}
There seems to be an issue with what is in ZK and what the TaskBatch holds. In
my case it could be related to the fact that the task was already in ZK after
many faulty restarts because of the NPE. Maybe it was added once (since that is
keyed by path, and that is unique on my machine), but the reference count upped
twice? Now that the real one is done, the done counter has been increased, but
will never match the scheduled.
