Hudson commented on HDFS-9902: ------------------------------ FAILURE: Integrated in Hadoop-trunk-Commit #9709 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/9709/]) HDFS-9902. Support different values of dfs.datanode.du.reserved per (arp: rev 6d77d6eab7790ed7ae2cad5b327ba5d1deb485db) * hadoop-hdfs-project/hadoop-hdfs/src/main/resources/hdfs-default.xml * hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/fsdataset/impl/FsVolumeImpl.java * hadoop-hdfs-project/hadoop-hdfs/src/test/java/org/apache/hadoop/hdfs/server/datanode/fsdataset/impl/TestFsVolumeList.java > Support different values of dfs.datanode.du.reserved per storage type > --------------------------------------------------------------------- > > Key: HDFS-9902 > URL: https://issues.apache.org/jira/browse/HDFS-9902 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Affects Versions: 2.7.2 > Reporter: Pan Yuxuan > Assignee: Brahma Reddy Battula > Attachments: HDFS-9902-02.patch, HDFS-9902-03.patch, > HDFS-9902-04.patch, HDFS-9902-05.patch, HDFS-9902.patch > > > Now Hadoop support different storage type for DISK, SSD, ARCHIVE and > RAM_DISK, but they share one configuration dfs.datanode.du.reserved. > The DISK size may be several TB and the RAM_DISK size may be only several > tens of GB. > The problem is that when I configure DISK and RAM_DISK (tmpfs) in the same > DN, and I set dfs.datanode.du.reserved values 10GB, this will waste a lot of > RAM_DISK size. > Since the usage of RAM_DISK can be 100%, so I don't want > dfs.datanode.du.reserved configured for DISK impacts the usage of tmpfs. > So can we make a new configuration for RAM_DISK or just skip this > configuration for RAM_DISK? -- 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
