Gabor Bota resolved HADOOP-15796. --------------------------------- Resolution: Cannot Reproduce Closing this as I was not able to reproduce the issue during the testing for HADOOP-15819 > ClassCastException: S3AFileSystem cannot be cast to MockS3AFileSystem when fs > caching is disabled > ------------------------------------------------------------------------------------------------- > > Key: HADOOP-15796 > URL: https://issues.apache.org/jira/browse/HADOOP-15796 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3 > Affects Versions: 3.1.1 > Reporter: Gabor Bota > Assignee: Gabor Bota > Priority: Major > > Sometimes we get {{java.io.IOException: s3a://TEST-BUCKET: FileSystem is > closed!}} when running tests, because of filesystem caching: an fs instance > is closed from a test teardown while another test is still using it. (That > should be fixed in another issue.) > To avoid test errors introduced by closed fs I've disabled fs caching while > testing. This caused the following issue in lots of test: > {noformat} > [ERROR] > testPartitionsResolution(org.apache.hadoop.fs.s3a.commit.staging.TestStagingPartitionedFileListing) > Time elapsed: 1.994 s <<< ERROR! > java.lang.ClassCastException: org.apache.hadoop.fs.s3a.S3AFileSystem cannot > be cast to org.apache.hadoop.fs.s3a.MockS3AFileSystem > at > org.apache.hadoop.fs.s3a.commit.staging.StagingTestBase.lookupWrapperFS(StagingTestBase.java:145) > at > org.apache.hadoop.fs.s3a.commit.staging.StagingTestBase$JobCommitterTest.setupJob(StagingTestBase.java:294) > {noformat} > We should fix the casting during these tests. > To switch of fs caching during a test (mvn verify) run, add the following to > the config: > {code:java} > <property> > <name>fs.s3a.impl.disable.cache</name> > <value>true</value> > </property> > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
