Hi there,   We are having problems when we try to run the process “Run Service Check” in HDFS. We proceed now to explain the steps taken:  When launching the "Run Service Check" process for HDFS in the DEVELOPMENT environment, the following error occurs:  Traceback (most recent call last):   File "/var/lib/ambari-agent/cache/stacks/HDP/3.0/services/HDFS/package/scripts/service_check.py", line 167, in     HdfsServiceCheck().execute()   File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 352, in execute     method(env)   File "/var/lib/ambari-agent/cache/stacks/HDP/3.0/services/HDFS/package/scripts/service_check.py", line 101, in service_check     params.kinit_path_local, False, None, params.smoke_user)   File "/usr/lib/ambari-agent/lib/resource_management/libraries/functions/curl_krb_request.py", line 201, in curl_krb_request     _, curl_stdout, curl_stderr = get_user_call_output(curl_command, user=user, env=kerberos_env)   File "/usr/lib/ambari-agent/lib/resource_management/libraries/functions/get_user_call_output.py", line 62, in get_user_call_output     raise ExecutionFailed(err_msg, code, files_output[0], files_output[1]) resource_management.core.exceptions.ExecutionFailed: Execution of 'curl --location-trusted -k --negotiate -u : -b /var/lib/ambari-agent/tmp/cookies/50a901c3-90db-44d5-8804-bd783a726294 -c /var/lib/ambari-agent/tmp/cookies/50a901c3-90db-44d5-8804-bd783a726294 http://im02.devprobdz.itbatera.ejgv.eus:8480 --connect-timeout 10 --max-time 12 1>/tmp/tmpd3De9R 2>/tmp/tmpNPnFs0' returned 28.   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                  Dload  Upload   Total   Spent    Left  Speed     0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:01 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:02 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:03 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:04 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:05 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:06 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:07 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:08 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:09 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:10 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:11 --:--:--     0   0     0    0     0    0     0      0      0 --:--:--  0:00:12 --:--:--     0 curl: (28) Operation timed out after 12001 milliseconds with 0 out of -1 bytes received   The curl request does not receive a response within the set time limit.

All tests are successful. When trying to launch the "Run Service Check" process again, it is observed that the failure occurs on different machines. Could you help us, please?   Regards.     ...
