Re: How more than one spark job can write to same partition in the parquet file
I have not got your question. Are you trying to write to a partition from two actions ?? or you are looking for writing from two jobs. Except for maintaining the state for the dataset completeness in that case, I dont see any issues.
We are writing data to a Partition using two different actions in a single spark job also partition here meant as a HDFS directory, not a hive partition.
