Asunto: Unintelligible warning arose out of the blue.
My setup is as follows:
Windows 10
Python 3.6.5
Spark 2.3.0
The latest java jdk
winutils/hadoop installed from this github page
https://github.com/steveloughran/winutils
I initialize spark from the pyspark shell as follows:
df = spark.read.csv('mvce.csv')
the mvce is a small file with 3 lines and 2 columns.
The warning I receive is:
2018-05-04 16:17:44 WARN ObjectStore:568 - Failed to get database global_temp,
returning NoSuchObjectException
What does this mean? I think it has something to do with YARN, but being an
internal technology I have no clue about it. It doesn't seem to be causing any
trouble, but I don't want to add the uncertainty that this might be causing an
bug in future diagnosing of issues.
Thank you for your help!
