---------------------------------
Summary: temporary directory for WriteOperation may not be unique
in FileBaseSink
Key: BEAM-7689
URL: https://issues.apache.org/jira/browse/BEAM-7689
Project: Beam
Issue Type: Bug
Components: io-java-files
Reporter: Heejong Lee
Assignee: Heejong Lee
Temporary directory for WriteOperation in FileBasedSink is generated from a
second-granularity timestamp (yyyy-MM-dd_HH-mm-ss) and unique id. Such
granularity is not enough to make temporary directories unique between
different jobs. When two jobs share the same temporary directory, output file
may not be produced in one job since the required temporary file can be deleted
from another job.
