Xiaoyu Yao updated HDFS-7608: ----------------------------- Fix Version/s: (was: 2.6.0) > hdfs dfsclient newConnectedPeer has no write timeout > ----------------------------------------------------- > > Key: HDFS-7608 > URL: https://issues.apache.org/jira/browse/HDFS-7608 > Project: Hadoop HDFS > Issue Type: Bug > Components: dfsclient, fuse-dfs > Affects Versions: 2.3.0, 2.6.0 > Environment: hdfs 2.3.0 hbase 0.98.6 > Reporter: zhangshilong > Assignee: Xiaoyu Yao > Labels: patch > Attachments: HDFS-7608.0.patch > > Original Estimate: 24h > Remaining Estimate: 24h > > problem: > hbase compactSplitThread may lock forever on read datanode blocks. > debug found: epollwait timeout set to 0,so epollwait can not run out. > cause: in hdfs 2.3.0 > hbase using DFSClient to read and write blocks. > DFSClient creates one socket using newConnectedPeer(addr), but has no read > or write timeout. > in v 2.6.0, newConnectedPeer has added readTimeout to deal with the > problem,but did not add writeTimeout. why did not add write Timeout? > I think NioInetPeer need a default socket timeout,so appalications will no > need to force adding timeout by themselives. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
