Uma Maheswara Rao G updated HIVE-24342:
---------------------------------------
Description:
Currently isPathEncrypted will make sure path is from hdfs by checking the path
scheme is "hdfs"
In the case if mounted ViewFileSystem based files systems like
ViewFSOverloadScheme or ViewHDFS (HDFS-15289) may need o check resolved path is
really hdfs.
In ViewHDFS case, we can mount hdfs://ns1/test ---> o3fs://b.v.ozone1/test
When user calling queries with the path hdfs://ns1/test, isPathEncrypted will
think the path is from hdfs only as its checking path scheme.
{code:java}
0: jdbc:hive2://umag-1.umag.root.xxx.site:218> select * from test30;
Error: Error while compiling statement: FAILED: SemanticException Unable to
determine if hdfs://ns1/test is encrypted:
java.lang.UnsupportedOperationException: This API:getEZForPath is specific to
DFS. Can't run on other fs:o3fs://bucket.volume.ozone1 (state=42000,code=40000)

{code}
So, here we should use resolvePath to make sure the resolved path really in
hdfs. If the resolved path is not from hdfs (in above case, it o3fs path), then
it will return false.
After fixing this, the query is passing.:
