Remote iterator does not work in compatibility mode

Details

    Description

      There are two issues when trying to iterate caches configured with compatibility:

      1) Since the client-side key tracker calculates segments based on byte[] keys, and the routing on the server is done via Object, there's a mismatch between segments calculated in the server and the client casing NPEs that prevent the data from the socket to be consumed correctly, resulting sometimes in:

      org.infinispan.client.hotrod.exceptions.InvalidResponseException:: Invalid magic number. Expected 0xa1 and received 0x0
	at org.infinispan.client.hotrod.impl.protocol.Codec20.readMagic(Codec20.java:313)
	at org.infinispan.client.hotrod.impl.protocol.Codec20.readHeader(Codec20.java:115)
	at org.infinispan.client.hotrod.impl.operations.HotRodOperation.readHeaderAndValidate(HotRodOperation.java:56)
	at org.infinispan.client.hotrod.impl.operations.IterationEndOperation.execute(IterationEndOperation.java:34)
	at org.infinispan.client.hotrod.impl.iteration.RemoteCloseableIterator.close(RemoteCloseableIterator.java:64)

      2) When the cache configuration has a different name than the cache, CCE errors are thrown:

      org.infinispan.client.hotrod.exceptions.HotRodClientException: java.lang.ClassCastException: java.lang.Integer cannot be cast to [B
	at org.infinispan.client.hotrod.impl.protocol.Codec20.checkForErrorsInResponseStatus(Codec20.java:343) ~[infinispan-client-hotrod-9.0.0-SNAPSHOT.jar:9.0.0-SNAPSHOT]

          causes

          Bug - A problem that impairs or prevents the functions of the product. ISPN-6543 Spark connector fails with CCE when compatibility mode is enabled

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
