Mikhail Petrov updated IGNITE-28348:
------------------------------------
Description:
We need to fix flaky DataReplicationOperationsTest. See
https://ci2.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=-2244900484209781876&tab=testDetails
for more details.
The cause of test failure is the ClientCacheRequest#cachex method which
searches for the requested cache descriptor and, if present, unconditionally
obtains corresponding cache proxy.
The cache proxy may not be initialized even if the cache descriptor is present
(PME caused by cache start is still in progress). In this case IgniteEx#cachex
returns null causing a NullPointerExeption.
We can consider the following ways to fix this issue:
- simply double check the cache existence after both calling
ClientCacheRequest#cacheDescriptor and IgniteEx#cachex.
- try using the cache proxy initialization wait mechanism - see
GridCacheProcessor#awaitInitializeProxy
