lastest HDP 2.6.5.0-292 DataFrame show() throws an error

Explorer

Hi ,

I'm using latest HDP ,version is 2.6.5.0-292. spark version is 2.3.0

when I'm trying to run show() from any DataFrame ,it always throw error :

scala> spark.read.csv("/user/a.txt").show()

I've tried both pyspark and spark-shell on 3 sets of newly installed hdp 2.6.5.0-292.

the DataFrame writing function works well ,only show() throws the error.

are there anyone encountered same issue as I had? how to fix this problem?

1 ACCEPTED SOLUTION

@dalin qin this type of errors are due multiple versions of same jar in classpath. Could you run

lsof -P -p <pid> | grep lz4

this will hopefully show the places from where the lz4 jar is being used and probably the incorrect version is being picked. Note: pid is the spark shell pid
