Subject [jira] [Commented] (HBASE-12393) The regionserver web will throw exception if we disable block cache
Date Fri, 31 Oct 2014 15:05:33 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12393?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14191900#comment-14191900
] 

ChiaPing Tsai commented on HBASE-12393:
---------------------------------------


It is only a little bug which we don't handle null point(cache block).
Maybe we can take null point as zero.
For example:
{code}
org.jamon.escaping.Escaping.HTML.write(org.jamon.emit.StandardEmitter.valueOf(StringUtils.humanReadableInt(checkSize(cacheConfig.getBlockCache()))),
jamonWriter);

static long checkSize(BlockCache blockCache)
{
    return blockCache == null ? 0 : blockCache.size();
}
{code}

>          Components: regionserver
>    Affects Versions: 0.98.7
>         Environment: ubuntu 12.04 64bits, hadoop-2.2.0, hbase-0.98.7-hadoop2

> 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.
> {code}
> org.jamon.escaping.Escaping.HTML.write(org.jamon.emit.StandardEmitter.valueOf(StringUtils.humanReadableInt(cacheConfig.getBlockCache().size())),
jamonWriter);
> {code}
