Yi Liu commented on HDFS-6357:
------------------------------

Thanks Uma. Great, we should log rpc id to editlog for retrycache. 
The patch is good. A small nit, the following line is a bit long..
{code}
-  void setXAttr(String src, XAttr xAttr, EnumSet<XAttrSetFlag> flag) 
+  void setXAttr(String src, XAttr xAttr, EnumSet<XAttrSetFlag> flag, boolean 
logRetryCache) 
       throws IOException {
{code}

> SetXattr should persist rpcIDs for handling Namenode restart and HA
