Subject [jira] [Updated] (SPARK-12519) "Managed memory leak detected" when using distinct on PySpark DataFrame
Date Thu, 24 Dec 2015 14:51:49 GMT

     [ https://issues.apache.org/jira/browse/SPARK-12519?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Paul Shearer updated SPARK-12519:
---------------------------------
    Description: 
After running the distinct() method to transform a DataFrame, subsequent actions like count()
and show() may report a managed memory leak. Here is a reproducible example:

h1. Script
{noformat}
logger = sc._jvm.org.apache.log4j
logger.LogManager.getLogger("org"). setLevel( logger.Level.WARN )
logger.LogManager.getLogger("akka").setLevel( logger.Level.WARN )

import string
import random
def id_generator(size=6, chars=string.ascii_uppercase + string.digits):
    return ''.join(random.choice(chars) for _ in range(size))

nrow   = 80000
ncol   = 20
ndrow  = 40000 # number distinct rows
tmp = [id_generator() for i in xrange(ndrow*ncol)]
tmp = [tuple(tmp[ncol*(i % ndrow)+0:ncol*(i % ndrow)+ncol]) for i in xrange(nrow)] 

dat = sc.parallelize(tmp,1000).toDF()
dat = dat.distinct()
ct = dat.count()
print ct  
# memory leak warning prints at this point in the code
dat.show()  
{noformat}

h1. Output

When this script is run in PySpark (with IPython kernel), I get this error:
{noformat}
