> TestLazyPersistReplicaRecovery#testDnRestartWithSavedReplicas fails

> Key: HDFS-13179
> URL: https://issues.apache.org/jira/browse/HDFS-13179
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: fs
> Affects Versions: 3.0.0
> Reporter: Gabor Bota
> Assignee: Ahmed Hussein
> Priority: Critical
> Attachments: HDFS-13179.001.patch, HDFS-13179.002.patch, test runs.zip

>
> The error caused by TimeoutException because the test is waiting to ensure
> that the file is replicated to DISK storage but the replication can't be
> finished to DISK during the 30s timeout in ensureFileReplicasOnStorageType(),
> but the file is still on RAM_DISK - so there is no data loss.
> Adding the following to TestLazyPersistReplicaRecovery.java:56 essentially
> fixes the flakiness.
> {code:java}
> try {
> ensureFileReplicasOnStorageType(path1, DEFAULT);
> }catch (TimeoutException t){
> LOG.warn("We got \"" + t.getMessage() + "\" so trying to find data on
> RAM_DISK");
> ensureFileReplicasOnStorageType(path1, RAM_DISK);
> }
> }
> {code}
> Some thoughts:
> * Successful and failed tests run similar to the point when datanode
> restarts. Restart line is the following in the log: LazyPersistTestCase -
> Restarting the DataNode
> * There is a line which only occurs in the failed test: *addStoredBlock:
> Redundant addStoredBlock request received for blk_1073741825_1001 on node
> 127.0.0.1:49455 size 5242880*
> * This redundant request at BlockManager#addStoredBlock could be the main
> reason for the test fail. Something wrong with the gen stamp? Corrupt
> replicas?
