> HBaseStorage has problems with processing multiregion tables
> ------------------------------------------------------------
>
> Key: PIG-1828
> URL: https://issues.apache.org/jira/browse/PIG-1828
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.8.0
> Environment: Hadoop 0.20.2, Hbase 0.20.6, Distributed mode
> Reporter: Lukas
> Assignee: Dmitriy V. Ryaboy
>
> As brought up in the pig user mailing list (http://www.mail-archive.com/user%40pig.apache.org/msg00606.html) Pig does sometime not scan the full HBase table.
> It seems that HBaseStorage has problems scanning large tables. It issues just one mapper job instead of one mapper job per table region.
> Ian Stevens, who brought this issue up in the mailing list, attached a script to reproduce the problem (https://gist.github.com/766929).
> However, in my case, the problem only occurred, after the table was split into more than one regions.
