Hi guys,   I was playind around with ACLs on a test cluster and set them recursively on /user to others::r-- instead of others::r-x. Then I wanted to change it back on /user/hive/warehouse but no matter what I do I cannot change them:   hdfs dfs -getfacl /user/hive/warehouse # file: /user/hive/warehouse # owner: hive # group: hive user::rwx user:hive:rwx group::--- group:hive:rwx mask::rwx other::--x   hdfs dfs -setfacl -m group::rwx /user/hive/warehouse   hdfs dfs -getfacl /user/hive/warehouse # file: /user/hive/warehouse # owner: hive # group: hive user::rwx user:hive:rwx group::--- group:hive:rwx mask::rwx other::--x   It always remains the same, I cannot change anything at all... Any ideas? ... View more

Hello,    I have installed a new cluster with CM 5.11 and Hadoop 2.6.0-cdh5.11.0. I have 1 Name Node with all other services running on it, and 2 Datanodes. HDFS Replication factor is set to 2.    I get the following  HDFS error: Bad : 666 under replicated blocks in the cluster. 675 total blocks in the cluster. Percentage under replicated blocks: 98.67%. Critical threshold: 40.00%.   I also tried setting the replication factor to 1 to test it out and restarted the cluster and agents, but the issue remains unchanged. There are a few threads about this issue already but I haven't found a solution yet. Do you have any idea? Thanks in advance! ... View more
