-----------------------------------------
Summary: HDFS copy thread in OutputHDFSFile is not removing files
that are processed
Key: AMBARI-17834
URL: https://issues.apache.org/jira/browse/AMBARI-17834
Project: Ambari
Issue Type: Bug
Components: ambari-logsearch
Reporter: Hemanth Yamijala
Consider the HDFS copy thread here:
https://github.com/apache/ambari/blob/trunk/ambari-logsearch/ambari-logsearch-logfeeder/src/main/java/org/apache/ambari/logfeeder/output/OutputHDFSFile.java#L177
It uses a data structure localReadyFiles that has the list of files to copy to
HDFS. But AFAICS, nowhere are processed files removed from this data structure.
This could result in multiple incorrect behaviours:
* Over a period of time, this structure could keep growing indefinitely. While
the check for existence of files will allow progress, it will take longer and
longer to run.
* The check to wait when there are no files to process will never pass because
the size of the data structure will never be 0. This could lead to tight looped
checks and some utilization issues.
