------------------------------------
With the change, when hbase mapredcp works, this script may not work any more.
For exmaple, on my cluster hbase mapredcp returns the following

> Change hive script to record errors when calling hbase fails
> ------------------------------------------------------------
>
> Key: HIVE-12058
> URL: https://issues.apache.org/jira/browse/HIVE-12058
> Project: Hive
> Issue Type: Bug
> Components: Hive, HiveServer2
> Affects Versions: 0.14.0, 1.1.0, 2.0.0
> Reporter: Yongzhi Chen
> Assignee: Yongzhi Chen
> Attachments: HIVE-12058.1.patch
>
>
> By default hive will try to find out which jars need to be added to the
> classpath in order to run MR jobs against an HBase cluster, however if hbase
> can't be found or if hbase mapredcp fails, the hive script will fail
> silently and ignore some of the jars to be included into the. That makes very
> difficult to analyze the real problem.
> Hive script should record the error not just simply redirect two hbase
> failures:
> HBASE_BIN=$
> {HBASE_BIN:-"$(which hbase 2>/dev/null)"}
> $HBASE_BIN mapredcp 2>/dev/null
