[jira] [Created] (HBASE-12575) sanity check coprocessor classes and other classes from configuration are loadable

Enis Soztutar created HBASE-12575:
-------------------------------------

             Summary: sanity check coprocessor classes and other classes from configuration are loadable
                 Key: HBASE-12575
                 URL: https://issues.apache.org/jira/browse/HBASE-12575
             Project: HBase
          Issue Type: Sub-task
            Reporter: Enis Soztutar
             Fix For: 2.0.0, 0.98.9, 0.99.2


We load coprocessors and other classes from configuration. In case of a typo in the class name (or deployment problem) a create table / alter table with wrong class name brings down the whole cluster. 

Master already does sanity check for compression and region split policy classes introduced in HBASE-10591. We should extend that to check some other common cases as well.
