ASF subversion and git services commented on NIFI-8787: ------------------------------------------------------- Commit 44779216658c55a2278dbc523ba1b4b08b8ef083 in nifi's branch refs/heads/main from Peter Gyori [ https://gitbox.apache.org/repos/asf?p=nifi.git;h=4477921 ] NIFI-8787: Wrapped hdfs.exists() call in UGI.doAs() in GetHDFS processor (#5217) * NIFI-8787: Wrapped hdfs.exists() call in UGI.doAs() in GetHDFS processor * NIFI-8787: Unit tests updated > GetHDFS hdfs.exists() call not wrapped in UGI.doAs() > ---------------------------------------------------- > > Key: NIFI-8787 > URL: https://issues.apache.org/jira/browse/NIFI-8787 > Project: Apache NiFi > Issue Type: Bug > Components: Extensions > Affects Versions: 1.14.0 > Reporter: Peter Gyori > Assignee: Peter Gyori > Priority: Major > Time Spent: 20m > Remaining Estimate: 0h > > In GetHDFS.performListing() before listing the files in the directory, it is > checked if the directory actually exists. > However, the hdfs.exists(directoryPath) call is not wrapped in UGI.doAs(). > HDFS operations should be wrapped in UGI.doAs() just like in NIFI-4323. > Also, it is important to call getUGI() before FileSystem operations because > that is where relogin and error handling is (like NIFI-7948). -- This message was sent by Atlassian Jira (v8.3.4#803005)
