----------------------------------
Summary: Create FileStatus.isEncrypted() method
Key: HDFS-6843
URL: https://issues.apache.org/jira/browse/HDFS-6843
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode, security
Affects Versions: fs-encryption (HADOOP-10150 and HDFS-6134)
Reporter: Charles Lamb
Assignee: Charles Lamb
FileStatus should have a 'boolean isEncrypted()' method. (it was in the context
of discussing with AndreW about FileStatus being a Writable).
Having this method would allow MR JobSubmitter do the following:
-----
BOOLEAN intermediateEncryption = false
IF jobconf.contains("mr.intermidate.encryption") THEN
intermediateEncryption = jobConf.getBoolean("mr.intermidate.encryption")
ELSE
IF (I/O)Format INSTANCEOF File(I/O)Format THEN
intermediateEncryption = ANY File(I/O)Format HAS a Path with status
isEncrypted()==TRUE
FI
jobConf.setBoolean("mr.intermidate.encryption", intermediateEncryption)
FI
