Akira AJISAKA commented on HDFS-8356:
-------------------------------------
Thanks [~rchiang] for updating the patch! Reviewed to
"dfs.namenode.name.cache.threshold".
# Would you document that
"dfs.namenode.available-space-block-placement-policy.balanced-space-preference-fraction"
is valid only if "dfs.block.replicator.classname" is set to
"org.apache.hadoop.hdfs.server.blockmanagement.AvailableSpaceBlockPlacementPolicy"?
# I'm thinking "dfs.namenode.edits.dir.minimum" is the minimum number of edits
dirs which have sufficient resources for the NameNode to continue operation.
Please see {{NameNodeResourcePolicy.java}} for the detail.
# In "dfs.namenode.edits.dir.required", the description in HDFS-3677 patch is
better, so I'll commit this. Would you remove the parameter from the patch?
# "dfs.namenode.kerberos.principal" and "dfs.namenode.keytab.file" can be
removed from the patch because they are already documented.
