Raju commented on HDFS-3734:
----------------------------
This is because of improper calculation of the blocksThreshold if I am not wrong
> TestFSEditLogLoader.testReplicationAdjusted() will hang if number of blocks
> are more than one

> Key: HDFS-3734
> URL: https://issues.apache.org/jira/browse/HDFS-3734
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.1.0-alpha, 3.0.0
> Reporter: Vinay
>
> TestFSEditLogLoader.testReplicationAdjusted() which was added in HDFS-2003
> will fail if number of blocks before cluster restart are more than one.
> Test Scenario:
> --------------
> 1. Write a file with min replication as 1 and replication factor as 1.
> 2. Change the min replication to 2 and restart the cluster.
> Expected: Min replication should be automatically reset on cluster restart by
> replicating more blocks.
> Currently, if the number of blocks before restart is only one, then on
> restart NN will not enter safemode, hence replication will happen and
> satisfies min replication factor.
> If initial blocks count is more than 1 which are having replication factor as
> 1, then on restart NN will enter safemode and will never come out.
