Subject [jira] [Commented] (HBASE-12393) The regionserver web will throw exception if we disable block cache
Date Fri, 31 Oct 2014 14:03:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12393?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14191818#comment-14191818
] 

Jean-Marc Spaggiari commented on HBASE-12393:
---------------------------------------------

Should we not simply throw exception when someone set the blockcache to 0 and not start the
RS?

> The CacheConfig.getBlockCache() will return the null point when we set hfile.block.cache.size
to zero.
> It caused the BlockCacheTmplImpl.java:123 to throw null exception.
