> I am running spark 1.4 and currently experiencing an issue when inserting data into a table. The data is loaded into an initial table and then selected from this table, processed and then inserted into a second table. The issue is that some of the data goes missing when inserted into the second table when running in a multi-worker configuration (a master, a worker on the master and then a worker on a different host). 
> I have narrowed down the problem to the insert into the second table. An example process to generate the problem is below. 
> Generate a file (for example /home/spark/test) with the numbers 1 to 50 on separate lines. 
> spark-sql --master spark://spark-master:7077 --hiveconf hive.metastore.warehouse.dir=/spark 
> (/spark is shared between all hosts) 
> create table test(field string); 
> load data inpath '/home/spark/test' into table test; 
> create table processed(field string); 
> from test insert into table processed select *; 
> select * from processed; 
> The result from the final select does not contain all the numbers 1 to 50. 
> I have also run the above example in some different configurations :- 
> - When there is just one worker running on the master. The result of the final select is the rows 1-50 i.e all data as expected. 
> - When there is just one worker running on a host which is not the master. The final select returns no rows.
> No errors are logged in the log files.
