In case > there are a large number of open operations coming in with access time update > on, since open does not call sync automatically, there is a possibility that > the buffer grow to a large size, therefore causes memory leak and full GC in > extreme cases as described in HDFS-1104. > The edit log buffer should be automatically flushed when the buffer becomes > full. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
