Subject [jira] [Commented] (HDFS-13237) [Documentation] RBF: Mount points across multiple subclusters
Date Thu, 05 Apr 2018 16:52:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16427238#comment-16427238

Wei Yan commented on HDFS-13237:

Sorry for the late. Some minors.
{quote}For deciding where to create a new file it uses the order parameter.
It currently supports the following methods:
The first '.' should be ','? Also would be better to "a new file" --> "a new file/folder".
{quote}* RANDOM: Random subcluster. This is usually useful for reading workloads and balance
the load across. Folders are created in all subclusters.
RANDOM can balance both READ and WRITE workload across subcusters, not just reading workload,
{quote}the difference is that HASH would make all the files/folder within a folder
Here "files/folder" should be "files/folders".
There is an extra '|' at the end.
