Resolution: Duplicate
> Spark History UI -- StreamConstraintsException: String length (20054016)
> exceeds the maximum length (20000000)
> --------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-49872
> URL: https://issues.apache.org/jira/browse/SPARK-49872
> Project: Spark
> Issue Type: Bug
> Components: UI
> Affects Versions: 3.5.3, 3.5.4
> Reporter: Anthony Sgro
> Priority: Major
> Labels: pull-request-available
>
> There is an issue with the Spark History UI with large amounts of event logs.
> The root of this problem is the breaking change in jackson that (in the name
> of "safety") introduced some JSON size limits, see:
> [https://github.com/FasterXML/jackson-core/issues/1014]
> Looks like {{JSONOptions}} in Spark already [support configuring this
> limit|https://github.com/apache/spark/blob/c2dbb6d04bc9c781fb4a7673e5acf2c67b99c203/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/json/JSONOptions.scala#L55-L58],
> but there seems to be no way to set it globally.
> Spark should be able to handle strings of arbitrary length. I have tried
> configuring rolling event logs, pruning event logs, etc. but this issue is
> not fixed or causes so much data loss that the spark history ui is completely
> useless.
> Perhaps a solution could be to add a config like:
> {code:java}
> spark.history.server.jsonStreamReadConstraints.maxStringLength=<new_value>
> {code}
> This has a workaround for reading JSON during your application:
> {code:java}
> spark.read.option("maxStringLen", 100000000).json(path) {code}
> But this is not an option for accessing the Spark History UI. Here is the
> full stack trace
> {code:java}
> HTTP ERROR 500
