SteNicholas opened a new pull request, #2517: URL: https://github.com/apache/celeborn/pull/2517
### What changes were proposed in this pull request? `TransportClientFactory` checks whether `handler` is null when creating client. ### Why are the changes needed? There is a case that `cachedClient.isActive()` may return true and may return false when checked for the second time when another thread is closing the channel, which causes that the `handler` may be null. Therefore, `TransportClientFactory` should check whether handler is null when creating client. Backport https://github.com/apache/spark/pull/46506. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested?
