Mingliang Liu commented on HDFS-15297: -------------------------------------- [~ayushtkn] I think the patch should work. The idea is to run directory scanner to update Datanode's volumeMap before sending BlockReports. So given this already is triggered, I think we can safely delete the sleep following this? {code:java} waitTil(TimeUnit.SECONDS.toMillis(DN_RESCAN_EXTRA_WAIT));{code} So this base test can run a little bit faster? > TestNNHandlesBlockReportPerStorage::blockReport_02 fails intermittently in > trunk > -------------------------------------------------------------------------------- > > Key: HDFS-15297 > URL: https://issues.apache.org/jira/browse/HDFS-15297 > Project: Hadoop HDFS > Issue Type: Bug > Components: test > Affects Versions: 3.4.0 > Reporter: Mingliang Liu > Priority: Major > Attachments: HDFS-15297-01.patch > > > It fails intermittently on {{trunk}} branch.
