Subject [jira] [Commented] (HDFS-14001) [PROVIDED Storage] bootstrapStandby should manage the InMemoryAliasMap
Date Fri, 07 Dec 2018 20:52:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-14001?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16713277#comment-16713277

Virajith Jalaparti commented on HDFS-14001:

 [^HDFS-14001.004.patch] removes the use of {{IO_FILE_BUFFER_SIZE}} in {{InMemoryAliasMap}}
for the copy and replaces this with the appropriate {{IOUtils.copyBytes}} method. This should
fix one of the checkstyle issues. I think we can ignore the others.

> Currently, we generate the fsimage and the alias map in one machine. When we start the
other NNs, we use bootstrapStandby to propagate the fsimage. However, we need to copy the
Alias Map by hand. We should copy also the Alias Map as part of this process.
