Brahma Reddy Battula updated HDFS-9038: --------------------------------------- Attachment: MAPREDUCE-6682.04.patch Uploaded the patch to fix the checkstyle issue and testcases fix. As ext filesystems will reserve 5% space which is not considered in non-dfs,hence {{TestNamenodeCapacityReport}} and {{TestNameNodeMetrics}} are failing.. > DFS reserved space is erroneously counted towards non-DFS used. > --------------------------------------------------------------- > > Key: HDFS-9038 > URL: https://issues.apache.org/jira/browse/HDFS-9038 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode > Affects Versions: 2.7.1 > Reporter: Chris Nauroth > Assignee: Brahma Reddy Battula > Attachments: GetFree.java, HDFS-9038-002.patch, HDFS-9038-003.patch, > HDFS-9038-004.patch, HDFS-9038-005.patch, HDFS-9038-006.patch, > HDFS-9038-007.patch, HDFS-9038-008.patch, HDFS-9038-009.patch, > HDFS-9038-010.patch, HDFS-9038.patch > > > HDFS-5215 changed the DataNode volume available space calculation to consider > the reserved space held by the {{dfs.datanode.du.reserved}} configuration > property. As a side effect, reserved space is now counted towards non-DFS > used. I don't believe it was intentional to change the definition of non-DFS > used. This issue proposes restoring the prior behavior: do not count > reserved space towards non-DFS used. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
