(Updated June 20, 2016, 4 a.m.)
Review request for atlas, Shwetha GS and Hemanth Yamijala.
Bugs: ATLAS-904
https://issues.apache.org/jira/browse/ATLAS-904
Repository: atlas
Description
-------
1. Process qualified name = HiveOperation.name + sorted inputs + sorted outputs
2. HiveOperation.name doesnt provide identifiers for identiifying INSERT,
INSERT_OVERWRITE, UPDATE, DELETE etc separately . Hence adding
WriteEntity.WriteType as well which exhibits the following behaviour
a. If there are multiple outputs, for each output, adds the query
type(WriteType)
b. if query being run if is type INSERT [into/overwrite] TABLE [PARTITION],
WriteType is INSERT/INSERT_OVERWRITE
b. If query is of type INSERT OVERWRITE hdfs_path, adds WriteType as PATH_WRITE
c. If query is of type UPDATE/DELETE, adds type as UPDATE/DELETE [ Note -
linage is not available for this since this is single table operation]
3.When input is of type local dir or hdfs path currently, it doesnt add it to
qualified name. The reason is that partition based paths cause a lot of
processes to be created in this case instead of updating the same process.
Pending:
Address Shwetha G S suggestion to add hdfs paths to process qualified name only
in case of non-partition based queries. This needs to be done per HiveOperation
type
1. if HiveOperation = LOAD, IMPORT, EXPORT - detect if the current query
context is dealing with partitions and do not add if it is partition based.
2. If HiveOperation = INSERT OVERWRITE DFS_PATH/LOCAL_PATH , then detect if the
query context is dealing with a partitioned table in inputs and decide if we
need to add or not.

Testing
-------
Existing tests modified to query with new qualified name. Need to add tests for
INSERT INTO TABLE
Thanks,
