Repository: usergrid Updated Branches: refs/heads/readRepairForIndexValues a67057909 -> 00171f07b
Added ignore to test for use case that doesn't currently work. Added ability to filter out multiple entities with the same user name ( pick the one one modified last ) Project: http://git-wip-us.apache.org/repos/asf/usergrid/repo Commit: http://git-wip-us.apache.org/repos/asf/usergrid/commit/2e8bc463 Tree: http://git-wip-us.apache.org/repos/asf/usergrid/tree/2e8bc463 Diff: http://git-wip-us.apache.org/repos/asf/usergrid/diff/2e8bc463 Branch: refs/heads/readRepairForIndexValues Commit: 2e8bc46329b11d5e625d75aad1b3dbb1d39e91ee Parents: 7db5769 Author: George Reyes <g...@apache.org> Authored: Tue Nov 10 12:22:41 2015 -0800 Committer: George Reyes <g...@apache.org> Committed: Tue Nov 10 12:22:41 2015 -0800 ---------------------------------------------------------------------- .../usergrid/tools/UniqueIndexCleanup.java | 104 +++++++++++++------ .../usergrid/tools/UniqueIndexCleanupTest.java | 2 +- 2 files changed, 73 insertions(+), 33 deletions(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/usergrid/blob/2e8bc463/stack/tools/src/main/java/org/apache/usergrid/tools/UniqueIndexCleanup.java ---------------------------------------------------------------------- diff --git a/stack/tools/src/main/java/org/apache/usergrid/tools/UniqueIndexCleanup.java b/stack/tools/src/main/java/org/apache/usergrid/tools/UniqueIndexCleanup.java index e835bec..c385b50 100644 --- a/stack/tools/src/main/java/org/apache/usergrid/tools/UniqueIndexCleanup.java +++ b/stack/tools/src/main/java/org/apache/usergrid/tools/UniqueIndexCleanup.java @@ -31,6 +31,7 @@ import org.apache.commons.cli.OptionBuilder; import org.apache.commons.cli.Options; import org.apache.thrift.TBaseHelper; +import org.apache.usergrid.persistence.Entity; import org.apache.usergrid.persistence.cassandra.EntityManagerImpl; import org.apache.usergrid.utils.StringUtils; import org.apache.usergrid.utils.UUIDUtils; @@ -138,9 +139,9 @@ public class UniqueIndexCleanup extends ToolBase { Keyspace ko = cass.getUsergridApplicationKeyspace(); Mutator<ByteBuffer> m = createMutator( ko, be ); - if (line.hasOption( APPLICATION_ARG ) || line.hasOption( COLLECTION_ARG ) || - line.hasOption( ENTITY_UNIQUE_PROPERTY_NAME ) || line.hasOption( ENTITY_UNIQUE_PROPERTY_VALUE ) ) { - deleteInvalidValuesForUniqueProperty(m ,line ); + if ( line.hasOption( APPLICATION_ARG ) || line.hasOption( COLLECTION_ARG ) || + line.hasOption( ENTITY_UNIQUE_PROPERTY_NAME ) || line.hasOption( ENTITY_UNIQUE_PROPERTY_VALUE ) ) { + deleteInvalidValuesForUniqueProperty( m, line ); } else { @@ -166,25 +167,22 @@ public class UniqueIndexCleanup extends ToolBase { Charset.defaultCharset() ).trim(); - - - //defensive programming, don't have to have to parse the string if it doesn't contain users. - if(returnedRowKey.contains( "users" )) { + if ( returnedRowKey.contains( "users" ) ) { String[] parsedRowKey = returnedRowKey.split( ":" ); //if the rowkey contains more than 4 parts then it may have some garbage appended to the front. if ( parsedRowKey.length > 4 ) { - parsedRowKey = garbageRowKeyParser(parsedRowKey); + parsedRowKey = garbageRowKeyParser( parsedRowKey ); - if(parsedRowKey == null) { + if ( parsedRowKey == null ) { System.out.println( returnedRowKey + " is a invalid row key, and unparseable.
