RE: Spark Dataframe write is hanging
Hi,
Were you able to find the root cause of this?
If yes, what was it?
The error indicates a network connection issue, so I guess
the solution should be about the network configuration.

Subject: Spark Dataframe write is hanging
Hi,
When I am saving Spark Dataframe to Ignite, the job sometimes get stuck with the attached error.
It seems to happen at random, and usualy at the end of the job (all the data has already been writen to Ignite)
Has anybody encountered this before?
