Subject [jira] [Commented] (HDFS-3891) QJM: SBN fails if selectInputStreams throws RTE
Date Thu, 06 Sep 2012 04:42:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13449411#comment-13449411
] 

Eli Collins commented on HDFS-3891:
-----------------------------------

You mean #2 btw, agree that's the right approach.

- JM#selectInputStreams could use an "@throws IOException if an error is encountered getting
edit input streams"
- Remove throws clause from JS#selectInputStreams

Otherwise +1, looks great

> Currently, QJM's {{selectInputStream}} method throws an RTE if a quorum cannot be reached.
This propagates into the Standby Node and causes the whole node to crash. It should handle
this error appropriately.
