rmuir commented on issue #1068: SOLR-14033: Fix Hadoop tests with security manager URL: https://github.com/apache/lucene-solr/pull/1068#issuecomment-563647313 I had two failures, both involved hadoop trying to execute to get unix supplementary groups: ``` [junit4] - org.apache.solr.cloud.TestSolrCloudWithSecureImpersonation (suite) [junit4] - org.apache.solr.security.hadoop.TestImpersonationWithHadoopAuth (suite) ``` Stacks look like this in both cases: ``` [junit4] ERROR 0.00s J0 | TestImpersonationWithHadoopAuth (suite) <<< [junit4] > Throwable #1: com.google.common.util.concurrent.UncheckedExecutionException: java.security.AccessControlException: access denied ("java.io.FilePermission" "<<ALL FILES>>" "execute") [junit4] > at __randomizedtesting.SeedInfo.seed([C1005F0247624]:0) [junit4] > at com.google.common.cache.LocalCache$Segment.get(LocalCache.java:2050) [junit4] > at com.google.common.cache.LocalCache.get(LocalCache.java:3951) [junit4] > at com.google.common.cache.LocalCache.getOrLoad(LocalCache.java:3973) [junit4] > at com.google.common.cache.LocalCache$LocalLoadingCache.get(LocalCache.java:4957) [junit4] > at org.apache.hadoop.security.Groups.getGroups(Groups.java:228) [junit4] > at org.apache.solr.security.hadoop.ImpersonationUtil.getUsersFirstGroup(ImpersonationUtil.java:42) [junit4] > at org.apache.solr.security.hadoop.TestImpersonationWithHadoopAuth.setupClass(TestImpersonationWithHadoopAuth.java:74) [junit4] > at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [junit4] > at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) [junit4] > at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [junit4] > at java.base/java.lang.reflect.Method.invoke(Method.java:567) [junit4] > at java.base/java.lang.Thread.run(Thread.java:830) [junit4] > Caused by: java.security.AccessControlException: access denied ("java.io.FilePermission" "<<ALL FILES>>" "execute") [junit4] > at java.base/java.security.AccessControlContext.checkPermission(AccessControlContext.java:472) [junit4] > at java.base/java.security.AccessController.checkPermission(AccessController.java:1036) [junit4] > at java.base/java.lang.SecurityManager.checkPermission(SecurityManager.java:408) [junit4] > at java.base/java.lang.SecurityManager.checkExec(SecurityManager.java:658) [junit4] > at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1096) [junit4] > at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1071) [junit4] > at org.apache.hadoop.util.Shell.runCommand(Shell.java:938) [junit4] > at org.apache.hadoop.util.Shell.run(Shell.java:901) [junit4] > at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:1213) [junit4] > at org.apache.hadoop.security.ShellBasedUnixGroupsMapping.getUnixGroups(ShellBasedUnixGroupsMapping.java:200) [junit4] > at org.apache.hadoop.security.ShellBasedUnixGroupsMapping.getGroups(ShellBasedUnixGroupsMapping.java:97) [junit4] > at org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback.getGroups(JniBasedUnixGroupsMappingWithFallback.java:51) [junit4] > at org.apache.hadoop.security.Groups$GroupCacheLoader.fetchGroupList(Groups.java:387) [junit4] > at org.apache.hadoop.security.Groups$GroupCacheLoader.load(Groups.java:321) [junit4] > at org.apache.hadoop.security.Groups$GroupCacheLoader.load(Groups.java:270) [junit4] > at com.google.common.cache.LocalCache$LoadingValueReference.loadFuture(LocalCache.java:3527) [junit4] > at com.google.common.cache.LocalCache$Segment.loadSync(LocalCache.java:2276) [junit4] > at com.google.common.cache.LocalCache$Segment.lockedGetOrLoad(LocalCache.java:2154) [junit4] > at com.google.common.cache.LocalCache$Segment.get(LocalCache.java:2044) [junit4] > ... 29 more ``` I haven't looked at what is going on here, maybe the user's supplementary groups could be retrieved instead via JAAS functionality, e.g. https://docs.oracle.com/javase/7/docs/jre/api/security/jaas/spec/com/sun/security/auth/module/UnixSystem.html ?
