[jira] [Commented] (HDFS-5269) Attempting to remove a cache
directive fails with NullPointerException.
[ https://issues.apache.org/jira/browse/HDFS-5269?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13784920#comment-13784920 ]
Andrew Wang commented on HDFS-5269:
-----------------------------------
Hey Chris, thanks for the report. I folded in a fix for this in HDFS-5190 since I was already poking around in {{CacheAdmin}}. I went with {{DistributedFileSystem}} taking a {{PathBasedCacheDescriptor}}, which it then unpacks it into a {{long}} to pass to the {{DFSClient}} API. {{CacheAdmin}} then calls the {{DFSClient}} API directly. Let me know if this works for you (a full review on HDFS-5190 would also be appreciated!).
