Dawid Weiss commented on SOLR-14033:
------------------------------------
Things work for me just fine on Windows and Linux!
If I enable a full hdfs set of tests with -Dtests.disableHdfs=false and run
from cmd (not cygwin) then I get thread leaks and this:
{code:java}
java.lang.UnsatisfiedLinkError: 'boolean
org.apache.hadoop.io.nativeio.NativeIO$Windows.access0(java.lang.String, int)'
at __randomizedtesting.SeedInfo.seed([5EC7AC29C87F9078]:0)
at org.apache.hadoop.io.nativeio.NativeIO$Windows.access0(Native Method)
at org.apache.hadoop.io.nativeio.NativeIO$Windows.access(NativeIO.java:645)
at org.apache.hadoop.fs.FileUtil.canWrite(FileUtil.java:1248) {code}
I think the entire "-Dtests.disableHdfs" thing can be removed and replaced with
a catch of UnsatisfiedLinkError above in HdfsTestUtil.setupClass. If this link
error happens and the system is Windows then the test should be
assumption-ignored. No need for a separate property and all this magic trickery.
