Summary: [SPS]: Storage Policy Satisfier daemon thread in Namenode to find the blocks which were placed in wrong storages than what NN is expecting. Key: HDFS-10800 URL: https://issues.apache.org/jira/browse/HDFS-10800 Project: Hadoop HDFS Issue Type: Sub-task Components: namenode Reporter: Uma Maheswara Rao G Assignee: Uma Maheswara Rao G This JIRA is for implementing a daemon thread called StoragePolicySatisfier in nematode, which should scan the asked files blocks which were placed in wrong storages in DNs. The idea is: # When user called on some files/dirs for satisfyStorage policy, They should have tracked in NN and then StoragePolicyDaemon thread will pick one by one file and then check the blocks which might have placed in wrong storage in DN than what NN is expecting it to. # After checking all, it should also construct the data structures for the required information to move a block from one storage to another. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
