Hello @intersoldi, Thanks for being part of our community. This could be an issue related to some threads blocked. Do you see anything on the YARN application log? On the Spark Event Log, does it always hang on the same task? Another thing you can try is to get jstacks and review them to see if they are hanging on any specific point or step, for example, a connection or thread.

Thank you for the great insights These are the disctp options distcp -skipcrccheck -copybuffersize 32768 -update -pugp -bandwidth 50 -strategy dynamic and yes, total execution time increases almost linearly with nr of files/directories

Cloudera Support helped me resolved this issue. * The "Bad Health" status displayed in Cloudera Manager was a false-positive monitoring alert. * The Cloudera Manager Service Monitor (SMON) was failing its secure TLS connection handshakes to ZooKeeper due to strict endpoint identification checks introduced in modern Java runtimes (Java 17). Because SMON couldn't pull health metrics, it flagged ZooKeeper as down. * The solution is to configure the JVM argument inside the SMON configuration "Java Configuration Options for Service Monitor (firehose_java_opts)" to bypass the strict certificate hostname checks: `-Djdk.rmi.ssl.client.enableEndpointIdentification=false`. This cluster is 7.1.9sp1 with 7.13.1 CM. Strangely, another cluster, which has the same cluster version, CM version, and Java version, had no such issue. It was set up six months ago. Thanks for all the responses. Best regards,

Here is another way... Instead of basic auth (user/pass), you could use Kerberos to authenticate the request programmatically. This removes the need for hardcoded credentials. Using Python (requests-kerberos): Python import requests from requests_kerberos import HTTPKerberosAuth knox_url = "https://<knox-host>:8443/gateway/knoxsso/api/v1/token" # This uses your existing kinit session response = requests.get(knox_url, auth=HTTPKerberosAuth(), verify=False) if response.status_code == 200: token_data = response.json() print(f"Your Token: {token_data['access_token']}") Set up a Kerberos keytab for your service account, and use a script (Python or Java) to hit the Knox Token API using SPNEGO. This is the enterprise-standard way to automate Knox token generation without the Web UI or manual password entry. I think there are quite a few alternatives here, java, nifi, etc
