Jonathan Hsieh updated HDFS-1787: --------------------------------- Attachment: hdfs-1787.3.patch needed to generate patch using git diff --no-prefix ... > "Not enough xcievers" error should propagate to client > ------------------------------------------------------ > > Key: HDFS-1787 > URL: https://issues.apache.org/jira/browse/HDFS-1787 > Project: Hadoop HDFS > Issue Type: Improvement > Components: data-node > Affects Versions: 0.23.0 > Reporter: Todd Lipcon > Assignee: Jonathan Hsieh > Labels: newbie > Fix For: 0.23.0 > > Attachments: hdfs-1787.2.patch, hdfs-1787.3.patch, hdfs-1787.patch > > > We find that users often run into the default transceiver limits in the DN. > Putting aside the inherent issues with xceiver threads, it would be nice if > the "xceiver limit exceeded" error propagated to the client. Currently, > clients simply see an EOFException which is hard to interpret, and have to go > slogging through DN logs to find the underlying issue. > The data transfer protocol should be extended to either have a special error > code for "not enough xceivers" or should have some error code for generic > errors with which a string can be attached and propagated. -- This message is automatically generated by JIRA.
