I have installed 0.16.0 rc 1 which I believe contains a fix for this
issue, but I still see the same problem.
- I am using a single node.
- The client application runs in a single thread, loading data into a
single table.
- I get good throughput of about 200 rows/sec to start with, with
occasional significant drops due to NotServingRegionException's that are
recoverable on client retry (internal to hbase).
- After 54 minutes, and about 500,000 rows I start to see
WrongRegionException's in the client application, i.e. real failures.
Are things improved at all? Were you able to do 500k rows with previous
hbase versions?
Send us over some of those WREs. We'd thought we'd fixed those.
- Throughput rapidly drops to only a few rows per minute plus a few rows
that had errors
Should I be adding these comments to the JIRA issue? I did not see a way
to reopen the issue; perhaps I just don't have the permission necessary.
Yeah, make a JIRA. Describe roughly the data type, sizes, and schema.
Want to send me your regionserver log? Do you have DEBUG enabled?
That'd help. (I have still to look at the log you sent me previous --
I'll get to it). Is it critical that this work all on one server only?
For example, would it be an option to run 4 servers?
