Shuyan Zhang updated HDFS-17190:
--------------------------------
Environment: (was: When we need to use OIV to print EC information for
a directory, `PBImageTextWriter#getErasureCodingPolicyName` will be called.
Currently, this method uses
`XATTR_ERASURECODING_POLICY.contains(xattr.getName())` to filter and obtain EC
XAttr, which is very dangerous. If we have an XAttr whose name happens to be a
substring of `hdfs.erasurecoding.policy`, then `getErasureCodingPolicyName`
will return the wrong result. Our internal production environment has
customized some XAttrs, and this bug caused errors in the parsing results of
OIV when using `-ec` option. )
> EC: Fix bug for OIV processing XAttr.
