Yongjun Thanks for letting us know. I looked into the JIRAs and didn’t see anything that might affect Ranger.

When we copy a file managed by the external attribute provider from one cluster to another, or within the same cluster, we want to avoid copying the meta data supplied by the external attribute provider and saving it to target HDFS. The reasons are, 1. we want to replicate only HDFS data; 2. we don't want to save potentially bad external data to HDFS fsimage which could corrupt HDFS. To address this issue, I created https://issues.apache.org/jira/browse/HDFS-12294. and HDFS-12295 Wonder if you guys have hit this issue, and any solution you applied? Would some of you please take a look at HDFS-12294 and HDFS-12295, and comment there with your thoughts? Thanks a lot. --Yongjun
