Vinayakumar B commented on HDFS-8270: ------------------------------------- Cherry-picked to 2.6.1 > create() always retried with hardcoded timeout when file already exists with > open lease > --------------------------------------------------------------------------------------- > > Key: HDFS-8270 > URL: https://issues.apache.org/jira/browse/HDFS-8270 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs-client > Affects Versions: 2.6.0 > Reporter: Andrey Stepachev > Assignee: J.Andreina > Fix For: 2.6.1, 2.7.1 > > Attachments: HDFS-8270-branch-2.6-v3.patch, > HDFS-8270-branch-2.7-03.patch, HDFS-8270.1.patch, HDFS-8270.2.patch, > HDFS-8270.3.patch > > > In Hbase we stumbled on unexpected behaviour, which could > break things. > HDFS-6478 fixed wrong exception > translation, but that apparently led to unexpected bahaviour: > clients trying to create file without override=true will be forced > to retry hardcoded amount of time (60 seconds). > That could break or slowdown systems, that use filesystem > for locks (like hbase fsck did, and we got it broken HBASE-13574). > We should make this behaviour configurable, do client really need > to wait lease timeout to be sure that file doesn't exists, or it it should > be enough to fail fast. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
