> Observer namenode network delay causing empty block location for
> getBatchedListing
> ----------------------------------------------------------------------------------
>
> Key: HDFS-17768
> URL: https://issues.apache.org/jira/browse/HDFS-17768
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 3.4.1
> Reporter: Dimas Shidqi Parikesit
> Priority: Major
> Labels: pull-request-available
>
> In our testing with the latest hdfs version (e8a64d0), we found a similar
> case to HDFS-16732 happening in getBatchedListing. During a
> getBatchedListing, if the block report of the observer nn is delayed, one or
> more of the listing results will return blocks without location.
> Steps to reproduce this bug:
> # Start a cluster with 1 observer namenode
> # Create an empty file
> # Inject network delay between observer nn and active nn to delay block
> report (or add sleep to the BlockReportProcessingThread of the observer).
> # Append file to add block
> # Send a batchedListPaths request using client API
> # Check that the result has block without location
> In HDFS-16732 and HDFS-13924, a check was added in getBlockLocations,
> getFileInfo, and getListing that checks whether the found blocks have valid
> locations. Missing locations indicate that the observer namenode is not
> up-to-date compared to the active namenode.
> We propose to add the same check to getBatchedListing. If any of the
> sub-listing return blocks without location then it will throw
> ObserverRetryOnActiveException and exit the function early. The entire
> batchedListing request will be then retried on active namenode.
> Your insights are very much appreciated. We will continue following up this
> issue until it is resolved.
