[jira] [Commented] (HBASE-22836) MemcachedBlockCache parameter error

["Xu Cang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-22836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16905645#comment-16905645 ] 

Xu Cang commented on HBASE-22836:
---------------------------------

So, if I understand you correctly, you meant,
{code:java}
public int getMaxSize() {
 return MAX_SIZE;
}{code}
should be

 
{code:java}
public int getMaxSize() {
 return CachedData.MAX_SIZE;
}{code}
Correct?

Do you want to submit a patch for this? Thanks.

> When cache a block，the expiration is always set MAX_SIZE (which is a static final field).
> MAX_SIZE was mistakenly thought to be the max size of block. In fact, this parameter represents the expiration of the cached block. MAX_SIZE should be set 0 which means forever.
