Lukas Majercak commented on HDFS-13283: --------------------------------------- Considering the implementation is minimal, I'd rather keep them all in the same file. What do you think [~virajith]? I'll wait for yetus to come with checkstyle before making changes > Percentage based Reserved Space Calculation for DataNode > -------------------------------------------------------- > > Key: HDFS-13283 > URL: https://issues.apache.org/jira/browse/HDFS-13283 > Project: Hadoop HDFS > Issue Type: New Feature > Components: datanode, hdfs > Reporter: Lukas Majercak > Assignee: Lukas Majercak > Priority: Major > Attachments: HDFS-13283.000.patch, HDFS-13283.001.patch > > > Currently, the only way to configure reserved disk space for non-HDFS data on > a DataNode is a constant value via {{dfs.datanode.du.reserved}}. This can be > an issue in non-heterogeneous clusters where size of DNs can differ. The > proposed solution is to allow percentage based configuration (and their > combination): > # ABSOLUTE > ** based on absolute number of reserved space > # PERCENTAGE > ** based on percentage of total capacity in the storage > # CONSERVATIVE > ** calculates both of the above and takes the one that will yield more > reserved space > # AGGRESSIVE > ** calculates 1. 2. and takes the one that will yield less reserved space > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
