Thanks, Sean!
It was actually on the Catalyst side of things, but I found where column
pruning pushdown is delegated to univocity, see [1].
I've tried setting the spark configuration
*spark.sql.csv.parser.columnPruning.enabled* to *False* and this prevents
the bug from happening. I am unfamiliar
I've found the problem!
It was indeed a local thingy!
$ cat ~/.mavenrc
MAVEN_OPTS='-XX:+TieredCompilation -XX:TieredStopAtLevel=1'
I've added this some time ago. It optimizes the build time. But it seems it
also overrides the env var MAVEN_OPTS...
Now it fails with:
[INFO] ---
I think it's another occurrence that I had to change or had to set
MAVEN_OPTS. I think this occurs in a way that this setting doesn't affect,
though I don't quite understand it. Try the stack size in test runner
configs

The vote is now closed and the vote passes. Thank you to everyone who took
the time to review and vote on this SPIP. I’m looking forward to adding
this feature to the next Spark release. The tracking JIRA is
https://issues.apache.org/jira/browse/SPARK-31357.

It starts in org.apache.spark.sql.execution.datasources.csv.CSVDataSource.
Yes univocity is used for much of the parsing.
I am not sure of the cause of the bug but it does look like one indeed. In
one case the parser is asked to read all fields, in the other, to skip one.
The pushdown helps
hi all,
Yesterday I filed a CSV parsing bug [1] for Spark, that leads to data
incorrectness when data contains sequences similar to the one in the
report.
I wanted to take a look at the parsing logic to see if I could spot the
error to update the issue with more information and to possibly
Yes I've seen this; the JVM stack size needs to be increased. I'm not sure
if it's env specific (though you and I at least have hit it, I think
others), or whether we need to change our build script.
In the pom.xml file, find "-Xss..." settings and make them something like
"-Xss4m", see if that
Hi,
I am not able to build Spark due to the following error :
