Spark setup

[George Davies]

I have already have a standalone ignite cluster running on k8s and can run
SQL statements against it fine.

Part of a requirements on the system i am building is to perform v-pivots
on the query result set.

I've seen spark come up as a good solution to v-pivots and so I'm trying to
set up a simple master + executor cluster.

I have added all the ignite libs to the classpath per the docs but when i
attempt to launch the master i get the error:

Error SparkUncaughtExceptionHandler:91 - Uncaught Exception in thread
Thread[main,5,main]
java.io.IOException: failure to login
Caused by: javax.security.auth.login.LoginException:
java.lang.NullPointerException: invalid null input: name

Any pointers on what I am doing incorrectly? I dont have a separate HDFS
cluster to log in to, I just want to use spark over the ignite caches.

Is there a way to re-set the index inline size at runtime?

per my understanding increase the index inline size can improve query
performance, so is there a way to increase the index inline size at runtime?
my guess is that drop and re-create index will cost the whole cluster a lot.
is that true?

Thanks,
