[jira] [Updated] (SPARK-2698) RDD pages shows negative bytes remaining for some executors

["Sean Owen (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-2698?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Owen updated SPARK-2698:
-----------------------------
    Priority: Minor  (was: Major)

This might have been fixed at some point since 1.0 though I don't see an obvious candidate. The problem is that "memUsed" exceeds "maxMem" in {{StorageStatus}}. It doesn't look like mere rounding error since the difference is >700MB out of 9.6GB. 

It's easy to make {{memRemaining}} never return a negative value, which is on the one hand good defensive programming but might be hiding a race condition or other logic error.

Any thoughts on whether that is more good than harm?
