[jira] [Created] (KUDU-2702) spark client data miss duing high load
write
Simon Zhang created KUDU-2702:
---------------------------------
Summary: spark client data miss duing high load write
Key: KUDU-2702
URL: https://issues.apache.org/jira/browse/KUDU-2702
Project: Kudu
Issue Type: Bug
Components: client, consensus, spark
Affects Versions: 1.8.0
Reporter: Simon Zhang
For our business, we need to write every signal into kudu, so the load is very hight. We decide to use spark stream will kudu client to fulfill this task. the logic like below:
{code:java}
val kuduContext = new KuduContext(taskArgs.get("KuduMaster"), trackRdd.sparkContext)
........
kuduContext.upsertRows(trackRdd, saveTable){code}
check spark log get the same issue like [[|https://jira.apache.org/jira/browse/KUDU-2329] [KUDU-2329|https://jira.apache.org/jira/browse/KUDU-2329] [|https://jira.apache.org/jira/browse/KUDU-2329]|https://jira.apache.org/jira/browse/KUDU-2329]

Then use kudu cluster ksck to check staus find some tablet unavailable
