Uma Maheswara Rao G commented on HDFS-6283:
-------------------------------------------
Thanks a lot Andrew for the documentation!
Here are my quick comments on the patch!
dfs.namenode.inode.xattrs.max-limits --> dfs.namenode.inode.xattrs.max-limit
{code}
* <<<dfs.namenode.inode.xattrs.name.max-length>>>
+
+ The maximum length of the name of an extended attribute. By default, this
limit is 64 characters.
+
+ * <<<dfs.namenode.inode.xattrs.value.max-length>>>
+
+ The maximum length of the value of an extended attribute. By default, this
limit is 16384 bytes.
{code}
Please update as per JIRA HDFS-6377
Also need update in hdfs-default.xml
XAttrCommands is from common code, so can you leave that changes in that file
here. May we can handle that improvement as part of HADOOP-10561?
Dump all extended *attribute* values associated with pathname --> Dump all
values of the extended *attributes* associated with pathname
Displays the extended *attribute* names and values --> Displays the names and
values of the extended *attributes* ?
> Write end user documentation for xattrs.
