[jira] [Updated] (APEXMALHAR-2281) ManagedState: race condition with put & asyncGet and bucket size doesn't account for entries in file cache

     [ https://issues.apache.org/jira/browse/APEXMALHAR-2281?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chandni Singh updated APEXMALHAR-2281:
--------------------------------------
    Description: 
There are 2 bugs:
1. Race condition with put and asyncGet. put(...) inserts a bucketedValue in the flash with value = null first. It sets the value afterwords. There is a possibility that the reader thread will get BucketedValue from flash and read the value as null.

2. Bucket size doesn't account for entries in fileCache
