Hi.   I user Claudera Manager to install Sentry, but can't.  Can't open /var/run/cloudera-scm-agent/process/1747-sentry-SENTRY_SERVER/supervisor_status: Permission denied.   Looks, i have no premissions.   sudo ls -lah /var/run/cloudera-scm-agent/process/1747-sentry-SENTRY_SERVER total 64K drwxr-x--x 3 sentry sentry 360 Feb 22 11:26 . drwxr-x--x 161 sentry root 3.2K Feb 22 11:26 .. -rw-r----- 1 sentry sentry 250 Feb 22 11:26 cloudera-monitor.properties -rw-r----- 1 sentry sentry 342 Feb 22 11:26 cloudera-stack-monitor.properties -rw------- 1 root root 5.1K Feb 22 11:26 config.zip -rw-r----- 1 sentry sentry 3.3K Feb 22 11:26 core-site.xml -rw-r----- 1 sentry sentry 511 Feb 22 11:26 creds.localjceks -rw------- 1 sentry sentry 1 Feb 22 11:26 exit_code drwxr-x--x 2 sentry sentry 80 Feb 22 11:26 logs -rw-r----- 1 sentry sentry 579 Feb 22 11:26 navigator.client.properties -rw------- 1 root root 3.1K Feb 22 11:26 proc.json -rw-r----- 1 sentry sentry 1.7K Feb 22 11:26 redaction-rules.json -rw------- 1 sentry sentry 762 Feb 22 11:26 sentry.keytab -rw-r----- 1 sentry sentry 2.4K Feb 22 11:26 sentry-log4j.properties -rw-r----- 1 sentry sentry 2.5K Feb 22 11:26 sentry-site.xml -rw-r----- 1 sentry sentry 315 Feb 22 11:26 ssl-client.xml -rw------- 1 root root 3.5K Feb 22 11:26 supervisor.conf -rw------- 1 root root 636 Feb 22 11:26 supervisor_status   So, i don't know how to solve this issue. But i see two ways: 1. Runs C-Manager as sudo 2. something with paths - any way to create its as sentry-user.     PS: or, i confused in users/roles. I don't know what linux-user starts C-Manager, what linux-user runs sentry installation. And how about roles (in Manager)? How it correlated with linux users? ... View more

Hi, i need to create new user and grant to it few rules (on select of couple schemas). i create group, create user, assign user to group, and see it in hdfs - and there're no groups.   1.  sudo adduser tezd_user 2.  sudo groupadd tezd_group 3. sudo usermod -a -G tezd_group tezd_user 4. groups tezd_user >> tezd_user : tezd_user tezd_group 5. hdfs groups tezd_user >> tezd_user :   So, user have no group - have to rules - have no access to any action in db. How to set group for user, and how to get rules to user (i think, it makes by addition group to user)? ... View more

Hi, i need to collect information like "create table" statment: table and schema names, columns and its types, comments and so on.   So, i'm able to collect table schema and table names and its location ("TBLS"), columns ("COLUMNS_V2") and table prooperties ("TABLE_PARAMS"). But i can't get any info about PK and partitions. Tables "PARTITIONS", "PARTITION_KEYS", "IDXS", "INDEX_PARAMS" are empty. So, i don't know where can i find information about. Where's it? Of course, i create table with partitions and primary keys.   Oh, and i should be get type of table too: parquete, textfile or kudu-table. Havn't this info too. ... View more

Where kudu stores it?     PS: i need to admin partitions - add it, drop it and so on... But i don't know where it stores, so i can't do anything. ... View more

Hi. I run Impala-shell command  impala-shell -i hdp01.***.***.ru:21051 -k -f /tmp/qql.sql and catch such error: Starting Impala Shell using Kerberos authentication Using service name 'impala' Error connecting: TTransportException, TSocket read 0 bytes Not connected to Impala, could not execute queries. That's all. No logs. No special error description. Noghing. Just "not connected to Impala".   However, Impala works fine. In Hue i can exec queries. And "host:port" is fine. If i set other combination of it, i get:  Starting Impala Shell using Kerberos authentication Using service name 'impala' Error connecting: TTransportException, Could not connect to any.other.port.ru:21050 So, we can see, that server available. But Impala is not.   Why? And how to fix it? I even can't google any solution by my error: "Error connecting: TTransportException, TSocket read 0 bytes" or "Not connected to Impala, could not execute queries."   Please, help me. ... View more
