Wei-Chiu Chuang created HDFS-12249: -------------------------------------- Summary: dfsadmin -metaSave to output maintenance mode blocks Key: HDFS-12249 URL: https://issues.apache.org/jira/browse/HDFS-12249 Project: Hadoop HDFS Issue Type: Bug Components: namenode Reporter: Wei-Chiu Chuang Assignee: Wellington Chevreuil Priority: Minor
Found while reviewing for HDFS-12182. {quote} After the patch, the output of metaSave is: Live Datanodes: 0 Dead Datanodes: 0 Metasave: Blocks waiting for reconstruction: 0 Metasave: Blocks currently missing: 1 file16387: blk_0_1 MISSING (replicas: l: 0 d: 0 c: 2 e: 0) 1.1.1.1:9866(corrupt) (block deletions maybe out of date) : 2.2.2.2:9866(corrupt) (block deletions maybe out of date) : Mis-replicated blocks that have been postponed: Metasave: Blocks being reconstructed: 0 Metasave: Blocks 0 waiting deletion from 0 datanodes. Corrupt Blocks: Block=0 Node=1.1.1.1:9866 StorageID=s1 StorageState=NORMAL TotalReplicas=2 Reason=GENSTAMP_MISMATCH Block=0 Node=2.2.2.2:9866 StorageID=s2 StorageState=NORMAL TotalReplicas=2 Reason=GENSTAMP_MISMATCH Metasave: Number of datanodes: 0 {quote} {quote} Looking at the output The output is not user friendly — The meaning of "(replicas: l: 0 d: 0 c: 2 e: 0)" is not obvious without looking at the code. Also, it should print maintenance mode replicas. {quote} -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
