Karthick commented on HBASE-21620:
----------------------------------
[~openinx] we removed the *(comparator.compare(nextKV, cell) > 0)* condition
and tested, but still the scan is slow.
> Problem in scan query when using more than one column prefix filter in some
> cases.

> In some cases, unable to get the scan results when using more than one column
> prefix filter.
> Attached a java file to import the data which we used and a text file
> containing the values..
> While executing the following query (hbase shell as well as java program) it
> is waiting indefinitely and after RPC timeout we got the following error..
> Also we noticed high cpu, high load average and very frequent young gc in
> the region server containing this row...
> scan 'namespace:tablename',\{STARTROW => 'test',ENDROW => 'test', FILTER =>
> "ColumnPrefixFilter('1544770422942010001_') OR
> ColumnPrefixFilter('1544769883529010001_')"}
> ROW COLUMN+CELL
> ERROR: Call id=18,
> waitTime=60005, rpcTimetout=60000
>
> Note: Table scan operation and scan with a single column prefix filter works
> fine in this case.
> When we check the same query in hbase-1.2.5 it is working fine.
> Can you please help me on this..
