Subject [jira] [Commented] (HBASE-12546) Validate schema options that require server side class availability
Date Tue, 25 Nov 2014 09:05:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14224264#comment-14224264

Jiajia Li commented on HBASE-12546:
-----------------------------------

hi, [~apurtell], I found that in hbase trunk: (https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java#L1169)
there is hcd check, such as check the regionsplitpolicy: (https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java#L1225),
but in 0.98 branch, the check is not found: (https://github.com/apache/hbase/blob/0.98/hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java#L1747)
, so does the sanityCheckTableDescriptor() function do the schema option validate? please
give me some advise, thanks~

> When processing table create and modification requests we should check the supplied schema
options for settings that require mentioned classes to be available from the regionserver
classpath (split policies, etc.). If we can't find the class on the classpath when processing
the admin request RPC, fail the operation immediately and return an exception rather than
allow problems later, such as aborts.
