Subject [jira] [Updated] (HDFS-11284) [SPS]: Avoid running SPS under safemode and fix issues in target node choosing.
Date Mon, 09 Jan 2017 07:21:59 GMT

     [ https://issues.apache.org/jira/browse/HDFS-11284?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yuanbo Liu updated HDFS-11284:
------------------------------
    Description:  When the real replication number of block doesn't match the replication
factor. For example, the real replication is 2 while the replication factor is 3, the satisfier
may encounter issue.  (was: Recently I've found in some conditions, SPS is not stable:
* SPS runs under safe mode.
* There're some overlap nodes in the chosen target nodes.
* The real replication number of block doesn't match the replication factor. For example,
the real replication is 2 while the replication factor is 3.)
