Hi everyone,

I have a cluster running Hadoop 0.20.3-snapshot with HBase 0.90.2.

I want to use bulk loading with HFileOutPutFormat, which works for me when
writing to 1 CF but fails for more.

I know this is solved in HBase 0.92 and my question is:

Can I upgrade from 0.90.2 to 0.92 without upgrading hadoop ? Will HBase
0.92 work the same with hadoop 0.20.3 ?

If not, is there a good patch anyone knows of ?

Thanks,

Amit.

Does hadoop 0.20.3 support append?

See '2.1.3. Hadoop' here http://hbase.apache.org/book.html#basic.prerequisites

As to your question, 0.92.x should work on same hadoop version as 0.90.x.

St.Ack

I can't find to much about append support on the web.  my full version is:
hadoop 0.20.3-r1057313

I did however check hbase-site.xml and hdfs-site.xmk for
dfs.support.append  property
and couldn't find it.
