Re: Drop column timeout

[James Taylor]

Hi Jacobo,
Please file a JIRA for asynchronous drop column functionality. There's a
few ways that could be implemented. We could execute the call that issues
the delete markers on the server-side in a separate thread (similar to what
we do with UPDATE STATISTICS), or we could support a map-reduce job that
executes the drop column. The former is easier, but wouldn't be resilient
against the cluster being bounced. It'd also put more load on the cluster
(but would execute faster). The latter would be a bit more work and with
the current framework, the MR job would need to be started manually.

You could remove the column manually from the SYSTEM.CATALOG, but you'd
want to bounce the region server hosting this table so that the cache gets
cleared (or call MetaDataService.clearTableFromCache() for the table).

Thanks,
James

Re: Drop column timeout

[Jacobo Coll]

Hi Flavio,

I was trying to find a different solution here. This doesn't seem like a
long term solution, as I expect the table to increase, and these new
timeouts may not be enough in the future. Also, I don't feel comfortable
increasing the timeouts that much.

Re: Drop column timeout

[Flavio Pompermaier]

I also had similar troubles and I fixed them changing the following params
(both on server and client side and restarting hbase):

hbase.rpc.timeout (to 60)
phoenix.query.timeoutMs (to 60)
hbase.client.scanner.timeout.period (from 1 m to 10m)
hbase.regionserver.lease.period (from 1 m to 10m)

I hope this could help you!

Drop column timeout

[Jacobo Coll]

Hi all,

I have a table in phoenix with 100M rows and ~3000 columns. I am trying to
remove some columns, but after some seconds, it fails with a timeout
exception:


0: jdbc:phoenix:> ALTER TABLE "ns"."table" DROP COLUMN IF EXISTS "myColumn";
Error: org.apache.phoenix.exception.PhoenixIOException: Failed to get
result within timeout, timeout=6ms (state=08000,code=101)

After this, the column is partially removed. Throws a "Error: ERROR 504

I can see values when adding this column as *Dynamic
