             Summary: Can not set coprocessor from Shell after HBASE-14224
                 Key: HBASE-14510
                 URL: https://issues.apache.org/jira/browse/HBASE-14510
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.98.14, 2.0.0, 1.3.0
            Reporter: Yerui Sun


I was able to set coprocessors for table by shell normally, but it didn't worked now.
Here's the shell output (omit really jar path and coprocessor classname)：
{code}
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell

I checked the recent commits and found HBASE-14224 is related to. It's an important improvement, but made a mistake in alter() of admin.rb, line 587. As the value is coprocess spec string but not only class name, here should use htd.setCoprocessorWithSpec instead of htd.setCoprocessor.
