Stephen Chu created HDFS-6205:
---------------------------------
Summary: FsShell setfacl can throw ArrayIndexOutOfBoundsException
when no perm is specified
Key: HDFS-6205
URL: https://issues.apache.org/jira/browse/HDFS-6205
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs-client
Affects Versions: 3.0.0, 2.4.0
Reporter: Stephen Chu
Priority: Minor
If users don't specify the perm of an acl when using the FsShell's setfacl
command, a fatal internal error ArrayIndexOutOfBoundsException will be thrown.
{code}
[root@hdfs-nfs ~]# hdfs dfs -setfacl -m user:bob: /user/hdfs/td1
-setfacl: Fatal internal error
java.lang.ArrayIndexOutOfBoundsException: 2

An improvement would be if it returned something like this:
{code}
[root@hdfs-nfs ~]# hdfs dfs -setfacl -m user:bob:rww /user/hdfs/td1
-setfacl: Invalid permission in <aclSpec> : user:bob:rww
Usage: hadoop fs [generic options] -setfacl [-R] [{-b|-k} {-m|-x <acl_spec>}
<path>]|[--set <acl_spec> <path>]
[root@hdfs-nfs ~]#
{code}
