Summary: Port webhdfs unmaskedpermission parameter to HTTPFS Key: HDFS-13170 URL: https://issues.apache.org/jira/browse/HDFS-13170 Project: Hadoop HDFS Issue Type: Improvement Reporter: Stephen O'Donnell HDFS-6962 fixed a long standing issue where default ACLs are not correctly applied to files when they are created from the hadoop shell. With this change, if you create a file with default ACLs against the parent directory, with dfs.namenode.posix.acl.inheritance.enabled=false, the result is: {code} # file: /test_acl/file_from_shell_off # owner: user1 # group: supergroup user::rw- user:user1:rwx #effective:r-- user:user2:rwx #effective:r-- group::r-x #effective:r-- group:users:rwx #effective:r-- mask::r-- other::r-- {code} And if you enable this, to fix the bug above, the result is as you would expect: {code} # file: /test_acl/file_from_shell # owner: user1 # group: supergroup user::rw- user:user1:rwx #effective:rw- user:user2:rwx #effective:rw- group::r-x #effective:r-- group:users:rwx #effective:rw- mask::rw- other::r-- {code} If I then create a file over HTTPFS or webHDFS, the behaviour is not the same as above: {code} # file: /test_acl/default_permissions # owner: user1 # group: supergroup user::rwx user:user1:rwx #effective:r-x user:user2:rwx #effective:r-x group::r-x group:users:rwx #effective:r-x mask::r-x other::r-x {code} Notice the mask is set to r-x and this remove the write permission on the new file. As part of HDFS-6962 a new parameter was added to webhdfs 'unmaskedpermission'. By passing it to a webhdfs call, it can result in the same behaviour as when a file is written from the CLI: {code} curl -i -X PUT -T test.txt --header "Content-Type:application/octet-stream" "http://host-10-17-103-28.coe.cloudera.comnamenode:50075/webhdfs/v1/test_acl/unmasked__770?op=CREATE&user.name=user1&namenoderpcaddress=namenode:8020&overwrite=false&unmaskedpermission=770" # file: /test_acl/unmasked__770 # owner: user1 # group: supergroup user::rwx user:user1:rwx user:user2:rwx group::r-x group:users:rwx mask::rwx other::--- {code} However, this parameter was never ported to HTTPFS. This Jira is to replicate the same changes to HTTPFS so this parameter is available there too. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
