[jira] [Updated] (HDFS-9351) No checkNNStartup() is called when fsck calls FSNamesystem.getSnapshottableDirs()
[ https://issues.apache.org/jira/browse/HDFS-9351?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Yongjun Zhang updated HDFS-9351: Description: I looked further at HDFS-9231 change I reviewed earlier, and realize I missed one thing. The patch changed {code} if (snapshottableDirs != null) { SnapshottableDirectoryStatus[] snapshotDirs = namenode.getRpcServer() .getSnapshottableDirListing(); if (snapshotDirs != null) { for (SnapshottableDirectoryStatus dir : snapshotDirs) { snapshottableDirs.add(dir.getFullPath().toString()); } } } {code} to {code} if (snapshottableDirs != null) { snapshottableDirs = namenode.getNamesystem().getSnapshottableDirs(); } {code} In old code, namenode.getRpcServer().getSnapshottableDirListing() calls checkNNStartup(), however, this is not done with the new code. This is a hole of the earlier HDFS-9231 patch. Create this jira to fix the hole. Suggest to revert this portion of the change, and add code to do what we need at NamenodeFsck. Sorry for missing this in my earlier review of HDFS-9231. Thanks. was: I looked further at HDFS-9231 change I reviewed earlier, and realize I missed one thing.

[jira] [Updated] (HDFS-9351) No checkNNStartup() is called when fsck calls FSNamesystem.getSnapshottableDirs()
[ https://issues.apache.org/jira/browse/HDFS-9351?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Xiao Chen updated HDFS-9351: Attachment: HDFS-9351.patch Thanks very much for the additional review and creating this JIRA. Good catch! I extracted that logic to {{FSNamesystem#getSnapshottableDirs}} method initially, but after some revs (patch004 in HDF-9231) that method is only called once and I should have reverted it anyways. My apologies for not doing so on the initial JIRA.
