Surendra Singh Lilhore commented on HDFS-13972:
-----------------------------------------------
Thanks [~crh] for the patch.
One issue I observed here in webhdfs, not sure we should handle here or not.
RouterWebHdfsMethods#redirectURI (Line #399) is replacing only the routerId in
redirected URL but is should replace the router token also with namenode token.
It should be same as RouterWebHdfsMethods#redirectURI ((Line #504).
{code:java}
// We modify the namenode location and the path
redirectLocation = redirectLocation
.replaceAll("(?<=[?&;])namenoderpcaddress=.*?(?=[&;])",
"namenoderpcaddress=" + router.getRouterId())
.replaceAll("(?<=[/])webhdfs/v1/.*?(?=[?])",
"webhdfs/v1" + path);{code}
Currently CREATE will fail without this change.{color}
