Imran Rashid updated SPARK-19796:
---------------------------------
Priority: Blocker (was: Major)
> taskScheduler fails serializing long statements received by thrift server
> -------------------------------------------------------------------------
>
> Key: SPARK-19796
> URL: https://issues.apache.org/jira/browse/SPARK-19796
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.2.0
> Reporter: Giambattista
> Priority: Blocker
>
> This problem was observed after the changes made for SPARK-17931.
> In my use-case I'm sending very long insert statements to Spark thrift server
> and they are failing at TaskDescription.scala:89 because writeUTF fails if
> requested to write strings longer than 64Kb (see
> https://www.drillio.com/en/2009/java-encoded-string-too-long-64kb-limit/ for
> a description of the issue).
> As suggested by Imran Rashid I tracked down the offending key: it is
> "spark.job.description" and it contains the complete SQL statement.
> The problem can be reproduced by creating a table like:
> create table test (a int) using parquet
> and by sending an insert statement like:
> scala> val r = 1 to 128000
> scala> println("insert into table test values (" + r.mkString("),(") + ")")
