-----------------------------
Summary: Speed up fsck
Key: HDFS-3998
URL: https://issues.apache.org/jira/browse/HDFS-3998
Project: Hadoop HDFS
Issue Type: Improvement
Components: name-node
Reporter: Ming Ma
We have some big clusters. Sometimes we want to find out the list of missing
blocks or blocks with only one replica quickly. Currently fsck has to take a
path as input and it then recursively check for inconsistency. That could take
a long time to find the missing blocks and the files the missing blocks belong
to. It will be useful to speed this up. For example, it could go directly to
missing blocks stored in NN and do the file lookup instead.
