- This analysis shows whether there is a data/time-skew for the data/time entering mapper tasks. + This Heuristic analysis the whole script code , find out any possible optimizations in the code . Optimization
+ will improve run time and compute efficiency of the code.

+ +

Explanation

+ + This Heuristic
+
    +
  1. Get the source code from code search
    2. +
  2. Analysis the complete source code and create DAG
    3. +
  3. Based on the shuffles happening inside each query generate the weight of the query
    4. +
  4. Then suggest based on the DAG analysis , what are the table can be converted to Views in Spark
    5. +
+

- This result of the analysis shows two groups of the spectrum, where the first group has significantly less input data compared to the second group. -

+ Specifically for ETL jobs , it is being observed that they follow a similar pattern in Hive .
+
    +
  1. Take the data from source tables
    2. +
  2. Create a lot of temporary/staging tables
    3. +
  3. Create final tables and delete temporary tables.
    4. +
+

+ + If we convert temporary tables to views in Spark , then multiple queries will get combined and unnecessary
+ shuffles and IO will be avoided in Spark . Since views in Spark consider as transformation , multiple hive
+ queries will get combined in Spark DAG .But converting all temporary tables to Spark , may lead to vary narrow
+ DAG in Spark ,which may lead to failure
+ +

Algorithm

+ + Hence this heuristics parses the whole hive script , create DAG where ,each hive query is node and
+ input and output tables are edges . Then based on number of shuffle operation in each node , complexity of the node
+ is decided. Then we traverse the DAG and if the weight of the path(sum of weight of total nodes traversed so far)
+ is greater then threshold , then that table would not be considered to convert into views .

+ + Above approach make sures that , there will be considerable tables converted in views and also make sure the Spark DAG
+ is not very narrow. + + +

Change only above mentioned tables to views and rest of the table as is and run through Spark . For .eg + +
