Subject [jira] [Commented] (HBASE-12575) Sanity check table coprocessor classes are loadable
Date Mon, 08 Dec 2014 00:49:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14237335#comment-14237335
] 

Andrew Purtell commented on HBASE-12575:
----------------------------------------

One of the shell tests fails a sanity check:
{noformat}
java.io.FileNotFoundException: File does not exist: hdfs:/foo.jar
	at org.apache.hadoop.hbase.master.HMaster.sanityCheckTableDescriptor(HMaster.java:1232)
{noformat}
So the test will need updating.

> 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.
