There was access issue for the files event-processor.log, das-webapp.log. Gave access to those files, which resolved DAS WebUI issue.

Hi, There was an issue of replication of Hive metadata to DAS; I was trying to resolve it by resetting tables by taking reference of "https://docs.cloudera.com/HDPDocuments/DAS/DAS-1.2.1/troubleshooting/content/das_replication_failure_in_event_processor.html". After executing SQL commands successfully; I was trying to start DAS. Under which "Data Analytics Studio Event Processor" was started successfully and running but "Data Analytics Studio Webapp" was started successfully but not running. Below is the configuration detail HDP - 3.0.1 DAS - 1.0.2.0.0 Steps I used; 1) Stops DAS from Ambari 2) taken backup of /var/log/das log files and created empty files of event-processor.log, das-webapp.log files. 3) Executed reset tables SQL commands to das database in postgres 4) Started DAS from Ambari. Other observations - 1) After start of DAS nothing is written in event-processor.log, das-webapp.log files. 2) But can see das.db_replication_info was getting refreshed with id = 2 database_name = * last_replication_id, last_replication_start_time, last_replication_end_time, next_replication_start_time with valid values. Could you please help me here for fixing replication issue in DAS. Is there any separate instructions to fix replication issue in DAS 1.0.2.0.0, since I referred instructions to fix replication issue in DAS-1.2.1. Let me know if any other information is needed. Your reply is awaited; Thanks!

Hi @Shelton Reason of this issue is https://docs.cloudera.com/HDPDocuments/DAS/DAS-1.4.4/troubleshooting/content/das_replication_failure_in_event_processor.html That I validated at my end, /var/log/das/event-processor.log is showing "Notification events are missing in the meta store" and /var/log/das/event-processor.log is showing replication is unsuccessful. I tried to follow instructions mentioned in above link to submit command curl -H 'X-Requested-By: das' -H 'Cookie: JSESSIONID=<session id cookie>' http(s) ://<hostname> :<port>/api/replicationDump/reset please refer screen print attached This command did not work, showing; {"code":404,"message": "HTTP 404 Not Found"} Could you please help here.

Hi @TimothySpann , Could you please let me know if you was able to resolve issue, since I am also facing similar issue. " Traceback (most recent call last): File "testhive.py", line 1, in <module> from pyhive import hive File "/usr/local/lib/python2.7/site-packages/pyhive/hive.py", line 10, in <module> from TCLIService import TCLIService File "/usr/local/lib/python2.7/site-packages/TCLIService/TCLIService.py", line 9, in <module> from thrift.Thrift import TType, TMessageType, TFrozenDict, TException, TApplicationException ImportError: No module named thrift.Thrift Any ideas?

@KWiseman Agreed, I did not have any other option to re-install HDP.

Hi cloudera Team, Following up for this issue;

shashank_naresh · ‎10-07-2019

I got the solution - I should send messages to sandbox-hdf.hortonworks.com and see those messages in HDF rather than HDP.

shashank_naresh · ‎10-07-2019

Hi @ManuelCalvo Yes it is connected;

Hi Cloudera Team, I am getting issue while sending message to Kafka topic from outside of sandbox, but same application in sandbox is able to send message to Kafka topic. Below is the screen print of these cases In First case I am trying to send test message to my Kafka topic; that application runs without giving any error. But at cluster location topic was not showing any messages In Second case when I ran the same application in sandbox messages were send and displayed in Kafka topic. Could you please assist me what wrong I am doing (or what extra I have to do) to make my First case successful.

I tried using successfully my sandbox/shell in box from another pc by configuring my sandbox in bridged adapter mode.

shashank_naresh · ‎10-06-2019

Hi, In Cloudera tutorial I've seen only below ways HDF (also HDP) can take data from exterior world; 1) scp 2) wget Could you please provide me sample example when sandbox can exchange data through other interfaces like; a) Kafka producer or Consumer outside of HDF (or CDA) sandbox b) Database (like MySQL) sitting outside of sandbox (in my case CDA) c) Any other file transmission mechanism other than scp. Thanks in advance for your guidance!

shashank_naresh · ‎10-03-2019

Thanks @kwabstian53 for reply, In my case target database will be hive, could you please also guide me what will the driver name and any documentation for setting up that driver in HDP. I've referred link "http://www.sql-workbench.net/manual/jdbc-setup.html" but not sure which driver to be used.

Hi, I am working on a project where we need to put data in Hive using Sqoop in HDP 3.0. That data is currently available on MySQL workbench which is running out side of HDP 3.0. Could you please let me know the steps/tutorial/example so that I can achieve it. Please note - I did not do any setup of Sqoop in HDP 3.0, not sure I need to install in Sqoop in HDP 3.0.

Thanks @Shelton ,it helps!

Hi, Just wanted to know if we can setup and use KNIME (A visual data analytics tool). I've tried to install in HDP 3.0 with the help of link "https://docs.knime.com/2018-12/server_installation_guide/index.html". Installation was successful but when I was trying to use link sandbox-hdf.hortonworks.com:8090, it was not connecting. In error log file I could see that "tomcat" was not able to connect localhost:8005. Not sure if this was the reason. Please let me know if anyone used KNIME in HDP sandbox. Or any Visual Data Analytics tool you have used. Thanks.

Hi Hortonworks Team, We are getting error "DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020" during pip install. I can see that HDP3.0/HDF3.2 are having python 2.7. My question is post January 1st, 2020. will HDP3.0/HDF3.2 stop working or we will not be able to install any python library through pip or there will be new release of HDP/HDF sandboxes with python version > 2.7.
