### What changes were proposed in this pull request? Updated kubernetes client. ### Why are the changes needed? https://issues.apache.org/jira/browse/SPARK-27812 https://issues.apache.org/jira/browse/SPARK-27927 We need this fix fabric8io/kubernetes-client#1768 that was released on version 4.6 of the client. The root cause of the problem is better explained in apache#25785 ### Does this PR introduce any user-facing change? Nope, it should be transparent to users ### How was this patch tested? This patch was tested manually using a simple pyspark job ```python from pyspark.sql import SparkSession if __name__ == '__main__': spark = SparkSession.builder.getOrCreate() ``` The expected behaviour of this "job" is that both python's and jvm's process exit automatically after the main runs. This is the case for spark versions <= 2.4. On version 2.4.3, the jvm process hangs because there's a non daemon thread running ``` "OkHttp WebSocket https://10.96.0.1/..." palantir#121 prio=5 os_prio=0 tid=0x00007fb27c005800 nid=0x24b waiting on condition [0x00007fb300847000] "OkHttp WebSocket https://10.96.0.1/..." palantir#117 prio=5 os_prio=0 tid=0x00007fb28c004000 nid=0x247 waiting on condition [0x00007fb300e4b000] ``` This is caused by a bug on `kubernetes-client` library, which is fixed on the version that we are upgrading to. When the mentioned job is run with this patch applied, the behaviour from spark <= 2.4.3 is restored and both processes terminate successfully Closes apache#26093 from igorcalabria/k8s-client-update.
