> In the case of all datanodes sending FBR when the namenode restarts (large
> clusters), there is an issue with incomplete block reporting
> ---------------------------------------------------------------------------------------------------------------------------------------
>
> Key: HDFS-17093
> URL: https://issues.apache.org/jira/browse/HDFS-17093
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 3.3.4
> Reporter: Yanlei Yu
> Priority: Minor
> Labels: pull-request-available
>
> In our cluster of 800+ nodes, after restarting the namenode, we found that
> some datanodes did not report enough blocks, causing the namenode to stay in
> secure mode for a long time after restarting because of incomplete block
> reporting
> I found in the logs of the datanode with incomplete block reporting that the
> first FBR attempt failed, possibly due to namenode stress, and then a second
> FBR attempt was made as follows:
> {code:java}
> ....
> 2023-07-17 11:29:28,982 INFO org.apache.hadoop.hdfs.server.datanode.DataNode:
> Unsuccessfully sent block report 0x6237a52c1e817e, containing 12 storage
> report(s), of which we sent 1. The reports had 1099057 total blocks and used
> 1 RPC(s). This took 294 msec to generate and 101721 msecs for RPC and NN
> processing. Got back no commands.
> 2023-07-17 11:37:04,014 INFO org.apache.hadoop.hdfs.server.datanode.DataNode:
> Successfully sent block report 0x62382416f3f055, containing 12 storage
> report(s), of which we sent 12. The reports had 1099048 total blocks and used
> 12 RPC(s). This took 295 msec to generate and 11647 msecs for RPC and NN
> processing. Got back no commands. {code}
> There's nothing wrong with that. Retry the send if it fails But on the
> namenode side of the logic:
> {code:java}
> if (namesystem.isInStartupSafeMode()
> && !StorageType.PROVIDED.equals(storageInfo.getStorageType())
> && storageInfo.getBlockReportCount() > 0) {
> blockLog.info("BLOCK* processReport 0x{} with lease ID 0x{}: "
> + "discarded non-initial block report from {}"
> + " because namenode still in startup phase",
> strBlockReportId, fullBrLeaseId, nodeID);
> blockReportLeaseManager.removeLease(node);
> return !node.hasStaleStorages();
> } {code}
> When a disk was identified as the report is not the first time, namely
> storageInfo. GetBlockReportCount > 0, Will remove the ticket from the
> datanode, lead to a second report failed because no lease
