Yanbo Liang commented on HDFS-3734: ----------------------------------- OK > 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. -- This message is automatically generated by JIRA.
