Arun Suresh updated HDFS-7718: ------------------------------ Attachment: HDFS-7718.1.patch [~cmccabe], Attaching initial patch as per your suggestion * Added a {{KeyProviderCache}} to the {{ClientContext}} * The {{DFSClient}} now obtains the KeyProvider from the cache. > DFSClient objects created by AbstractFileSystem objects created by > FileContext are not closed and results in thread leakage > --------------------------------------------------------------------------------------------------------------------------- > > Key: HDFS-7718 > URL: https://issues.apache.org/jira/browse/HDFS-7718 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Arun Suresh > Assignee: Arun Suresh > Attachments: HDFS-7718.1.patch > > > Currently, the {{FileContext}} class used by clients such as (for eg. > {{YARNRunner}}) creates a new {{AbstractFilesystem}} object on > initialization.. which creates a new {{DFSClient}} object.. which in turn > creates a KeyProvider object.. If Encryption is turned on, and https is > turned on, the keyprovider implementation (the {{KMSClientProvider}}) will > create a {{ReloadingX509TrustManager}} thread per instance... which are never > killed and can lead to a thread leak -- This message was sent by Atlassian JIRA (v6.3.4#6332)
