Subject RE: Help with secondary index
Date Tue, 21 Jul 2015 19:05:19 GMT
Perfect.

One quick followup, if I can: should this work on a table with a ton of data in it?

My create index command ran for about 10 minutes, and then failed with this error: [CREATE
- 0 row(s), 0.000 secs]  [Error Code: 101, SQL State: 08000]  null

Any ideas?

For (1):
ALTER TABLE fma.er_keyed_gz_meterkey_split_custid SET IMMUTABLE_ROWS=true;

For (2):
You won't need that property if your table is immutable, but it'd still be good to add it
for if/when you use mutable secondary indexes. Not sure which of those you'd need to add it
to - maybe all of them to be safe? See https://phoenix.apache.org/secondary_indexing.html#Setup
for a full list of properties you need

For (3):
Yes, should be hbase-site.xml. Thanks for letting us know.

This is my first time messing with a secondary index in Phoenix.

I used this syntax:

create index fma_er_keyed_gz_endpoint_id_include_sample_point on fma.er_keyed_gz_meterkey_split_custid
(endpoint_id) include (sample_point) SALT_BUCKETS = 550;

and I get this error:

[Error Code: 1029, SQL State: 42Y88]  ERROR 1029 (42Y88): Mutable secondary indexes must have
the hbase.regionserver.wal.codec property set to org.apache.hadoop.hbase.regionserver.wal.IndexedWALEditCodec
in the hbase-sites.xml of every region server tableName=FMA_ER_KEYED_GZ_ENDPOINT_ID_INCLUDE_SAMPLE_POINT

I have 2 questions and 1 (tiny) bug:

1) This table wasn’t declared as immutable, but functionally, it is. Is there a way to alter
the table to add the IMMUTABLE_ROWS property so that this will work? The table has over 10
billion rows, so I don’t want to recreate it if I can help it.

2) My region servers have all the following hbase-site.xml files. Which one(s) do I alter?
And do I need to restart hbase afterwards?

/etc/hbase/conf/hbase-site.xml
/var/lib/ambari-agent/cache/stacks/HDP/2.1.GlusterFS/services/HBASE/configuration/hbase-site.xml
/var/lib/ambari-agent/cache/stacks/HDP/2.2/services/HBASE/configuration/hbase-site.xml
/var/lib/ambari-agent/cache/stacks/HDP/2.0.6.GlusterFS/services/HBASE/configuration/hbase-site.xml
/var/lib/ambari-agent/cache/stacks/HDP/1.3.2/services/HBASE/configuration/hbase-site.xml
/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/services/HBASE/configuration/hbase-site.xml
/usr/hdp/2.2.0.0-2041/etc/hbase/conf.dist/hbase-site.xml
/usr/hdp/2.2.0.0-2041/phoenix/bin/hbase-site.xml

3) In the error message, hbase-sites.xml should be hbase-site.xml, correct?

Thanks!
