----------------------------------------

             Summary: Wrong initial BitSet size in GridPartitionStateMap
                 Key: IGNITE-6977
                 URL: https://issues.apache.org/jira/browse/IGNITE-6977
             Project: Ignite
          Issue Type: Bug
          Components: general
    Affects Versions: 2.1
            Reporter: Alexander Belyak


In constructor of org.apache.ignite.internal.utilGridPartitionStateMap(int parts) {
        states = new BitSet(parts);
    }
we initialize BitSet with part bit, but use private static final int BITS for each partition
state. As result long[] in BitSet get difficult predictable size (depends of access order
it can be exact as needed or almost twice bigger with at least one additional array copying)
