Thanks @zhangshuyan0 . > EC: Fix bug of OIV processing XAttr. > ------------------------------------ > > Key: HDFS-17190 > URL: https://issues.apache.org/jira/browse/HDFS-17190 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Shuyan Zhang > Priority: Major > Labels: pull-request-available > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
