Robert Muir commented on SOLR-13986:
------------------------------------
I implemented patch with my workaround from before.
Note that 2 tests still fail: HdfsThreadLeakTest, TestHdfsCloudBackupRestore
The problem is hadoop test code
(MiniDFSCluster.createPermissionsDiagnosisString):
https://github.com/apache/hadoop/blob/7a3188d054481b9bd563e337901e93476303ce7f/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileUtil.java#L1260
It calls File.canExecute, but doesn't handle SecurityException. This is clearly
documented in the java.io.File api:
https://docs.oracle.com/javase/7/docs/api/java/io/File.html#canExecute()
I think I can hack around it but someone should really do something about this
hadoop code.

> Project: Solr

> If we don't really need to execute processes, we can take the permission
> away. That way any attempt to execute something results in a
> SecurityException rather than running a process.
> It is necessary to first fix the tests policy before thinking about
> supporting securitymanager in solr. This way we can ensure functionality does
> not break via our tests.
