@zxcware  Please follow below discussion, hopefully you will get the answers:   Paywall question: https://community.cloudera.com/t5/Support-Questions/How-do-I-get-repository-credentials/m-p/311145#M224492 https://community.cloudera.com/t5/Support-Questions/https-archive-cloudera-com-cm6-6-2-0-ubuntu1604-displaying/m-p/311060#M224430   Long story short every Cloudera bits is behind Paywall now. You need a valid subscription for that Except you can Try the CDP latest version but not any Older version.  ... View more

@haxsaansiddiqi This is expected. There seems to be a confusion about the different products.  What you are doing is installing Private Cloud Experiences (Means CML, CDW & CDE etc.) which Needs a CDP Private Cloud Base Cluster which is synonyms of CDH/CM cluster in old days.  CDP Experience don’t have TRIAL available that’s what the error says Installation of the Kubernetes components of the CDP experience needs a License.  So if you want CDP Private Cloud Base cluster for TRIAL it's available and you can play around using the doc:  https://www.cloudera.com/downloads/cdp-private-cloud-trial.html & https://docs.cloudera.com/cdp-private-cloud-base/7.1.4/installation/topics/cdpdc-trial-installation.html   For Experience install you have to contact Sales Team to get the License.

@exploer The role logs needs to be in given format because at every start of service CM creates a runtime process directory as well for the Role logs it has rotation for logs after a given period of time/size. So the mm-dd-yy after logs makes it convenient and hard coded.  ... View more

@Narendra_ No, For production purposes you have to buy subscription given that Cloudera software can’t be setup without using Ambari and Cloudera Manager and you can’t effectively monitor the cluster.    You can install Hadoop Open Source version (Vanilla) but you are on own and will not get any Cloudera Support on that.  ...

@Sam2020 This is because Cloudera recently changed the download policy and now to download Cloudera Software you need a valid subscription.  Please see the announcement here: Transition to private repositories for CDH, HDP and HDF This is because of recent changes with respect to Paywall. Same has been answered in below thread : https://community.cloudera.com/t5/Support-Questions/http-public-repo-1-hortonworks-com-ambari-centos...   One solution would be to download the installed (Trial version from here)  $ wget https://archive.cloudera.com/cm7/7.1.4/cloudera-manager-installer.bin $ chmod u+x cloudera-manager-installer.bin $ sudo ./cloudera-manager-installer.bin For more details on Trial see: https://www.cloudera.com/downloads/cdp-private-cloud-trial.html ...

@sur I believe you have to Set below properties before executing create table statement .  SET hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager; SET hive.support.concurrency=true; This seems a very known behaviour and I did a simple Googling and found the solutions on several places.

@sur I believe you have to run the queries over Impala not Hive. I have tested below and it works several time in the past.  # Install Libraries !pip3 install impyla==0.13.8 !pip3 install thrift_sasl==0.2.1 !pip3 install thrift==0.9.3 !pip3 install sasl==0.2.1 # Connect to Impala from impala.dbapi import connect conn = connect(host='host', port=21050, auth_mechanism='GSSAPI', use_ssl=True, kerberos_service_name='impala') # Execute Query sql = "select * from table" cursor = conn.cursor() cursor.execute(sql) results = cursor.fetchall() You can refer the below doc: https://docs.cloudera.com/cdsw/1.9.1/import-data/topics/cdsw-running-queries-on-impala-tables.html ...

@rok The Threshold value look less here. To avoid getting the reported health alerts we recommend to increase the corresponding configuration values: CM -> Cloudera Management Services -> Configuration -> Search for "Descriptor Fetch Max Tries" CM -> Cloudera Management Services -> Configuration -> Event Server -> Search for "Descriptor Fetch Tries Interval" and change this value for all the roles. We would recommend to increase the "Descriptor Fetch Max Tries" value from the default 5 to 10 in a first step. I after that you are facing the issue than you should look at the agent logs and start from there.  ... View more

@innominate Please refer the below doc that will give you some idea.  Cloudera Manager automatically sets   nproc   configuration in   /etc/security/limits.conf, but this configuration can be overridden by individual files in   /etc/security/limits.d/. This can cause   problems   with Apache Impala and other components. Make sure that the   nproc   limits are set sufficiently high, such as   65536   or   262144. 1. https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_os_requirements.html 2. https://docs.cloudera.com/runtime/7.2.9/configuring-hbase/topics/hbase-configure-ulimit-pam-cli.html ...
