------------------------------------
Summary: Revise the implementation of FsPermissionChecker to take
Ranger policies into consideration
Key: IMPALA-12994
URL: https://issues.apache.org/jira/browse/IMPALA-12994
Project: IMPALA
Issue Type: Task
Components: Frontend
Reporter: Fang-Yu Rao
Assignee: Fang-Yu Rao
Impala's current implementation of
[FsPermissionChecker|https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/util/FsPermissionChecker.java]
does not take into consideration the Ranger policies on HDFS or the underlying
file system, which could result in unwanted AnalysisException during query
analysis phase as reported in IMPALA-11871 and IMPALA-12291. We should consider
revising FsPermissionChecker to consider the Ranger policies on the storage
layer as well.
