Akira AJISAKA commented on HDFS-8356:
-------------------------------------
Thank you [~rchiang] for the update! Reviewed to
"dfs.datanode.min.supported.namenode.version".
# Duplicate "during" in the description of "dfs.client.read.prefetch.size".
# In "dfs.client.read.short.curcuit.replica.stale.threshold.ms", "local read
short circuit" should be "short-circuit local reads".
# Would you make the order of "name", "value", "description" consistent?
# In "dfs.data.transfer.client.tcpnodelay", the parameter affects only when
creating sockets for write pipeline, so it's better to write as "If true, set
TCP_NODELAY to sockets for transferring data from DFS client."
# Would you document that "dfs.datanode.balance.max.concurrent.moves" is
reconfigurable via dfsadmin -reconfig command?
# "dfs.datanode.duplicate.replica.deletion" is for testing only, so would you
remove it from hdfs-default.xml?
# In "dfs.datanode.fsdataset.volume.choosing.policy", would you mention that
"If you would like to take into account available disk space, set the value to
"org.apache.hadoop.hdfs.server.datanode.fsdataset.AvailableSpaceVolumeChoosingPolicy"."?
# Would you remove "dfs.datanode.kerberos.principal" and
"dfs.datanode.keytab.file", which are already documented?
