[jira] [Commented] (HDFS-13916) Distcp SnapshotDiff to support WebHDFS

-
{quote}When there are millions of diffs between two snapshots, the old
getSnapshotDiffReport() isn't scalable. NameNode find itself creating huge RPC
messages for the snapshot diff items, which creates GC memory pressure;
application produces big memory spikes too.
{quote}
Yeps, True, have seen bunch of cases where this causes problem at the namenode
side. we should ultimately support getSnapshotDiffReportListing in WebHdfs.
Otherwise the code changes LGTM. If [~weichiu] is convinced we can have a
followup Jira to support {{getSnapshotDiffReportListing}} in {{WebHDFS}} and
can get this in to get the basic functionality support with {{WebHDFS}}

> [~ljain] has worked on the JIRA: HDFS-13052 to provide the possibility to
> make DistCP of SnapshotDiff with WebHDFSFileSystem. However, in the patch,
> there is no modification for the real java class which is used by launching
> the command "hadoop distcp ..."
>
> You can check in the latest version here:
> [https://github.com/apache/hadoop/blob/branch-3.1.1/hadoop-tools/hadoop-distcp/src/main/java/org/apache/hadoop/tools/DistCpSync.java#L96-L100]
> In the method "preSyncCheck" of the class "DistCpSync", we still check if the
> file system is DFS.
> So I propose to change the class DistCpSync in order to take into
> consideration what was committed by Lokesh Jain.

[jira] [Commented] (HDFS-16067) Support Append API in NNThroughputBenchmark
[
https://issues.apache.org/jira/browse/HDFS-16067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17369828#comment-17369828

Ayush Saxena commented on HDFS-16067:
-
* What are we doing with this:
{code:java}
HdfsFileStatus status = blkWithStatus.getFileStatus();
{code}
the {{status}} seems to be unused?
* For EC files we need to pass the new block flag, I guess we should allow an
option to use the new block flag as well for append. erasure coded files can
not be appended without that. for replicated files also the new block flag is
used in a bunch of cases. Good to add an option for that.
* Possible to extend a test case in {{TestNNThroughputBenchmark}}
* nit: Break line after override
{code:java}
849@Override long executeOp(int daemonId, int inputIdx, String ignore)
{code}
