Subject Re[2]: Kudu with Spark (Scanner not found. It may have expired)
Date Tue, 02 Apr 2019 06:42:59 GMT
Thanks Grant

I have upgraded Kudu Client (with kudu-spark, so i have tried client 1.9.0 with Kudu cluster
1.8.0) but still have this issue
This is especially noticeable for big tables ( with 10 000 000 000 records) 
Apache spark job failed after 4 attempts to find scanner and we can't process such tables
in kudu

Regards, Dmitry Pavlov
