Hi mauricio, Impala currently does not support graceful node decommissioning. We're tracking work on this feature in IMPALA-1760, but we currently are not targeting it for a particular release. Unfortunately that only leaves the option of killing the daemon. Cheers, Lars

We have workaround first point is inplace but we have experienced connection establishment issues from webserver to impala with below error. It got fixed itself after couple of hours and would like to know what causes this behavior. [Simba][ImpalaJDBCDriver](500176) Error connecting to HiveServer2, please verify connection details. Please help us to understand what causes this issue. Thank you, Aj

I'm not sure there are risks specifically. The best practice is to use Cloudera manager to configure memory limits for different services, so this is the right way to configure things. Cloudera Manager does have support to help set up memory limits for applications: https://www.cloudera.com/documentation/enterprise/latest/topics/cm_mc_autoconfig.html#concept_xjy_vb3_rn . For a production system, it's important to put thought into how much memory your system needs and how it's allocated between different services. E.g. as an earlier poster saw, 256MB is not enough memory to do much interesting with Impala.

Your comment gave me the clue, when I generated the script, I missed the statment that follows: ROW FORMAT DELIMITED, namely, -FIELDS TERMINATED BY ','. So the correct create statement would be: CREATE EXTERNAL TABLE IF NOT EXISTS ccce_apl( APL_LNK INT, UPDT_DTTM CHAR(26), UPDT_USER CHAR(8), RLS_ORDR_MOD_CD CHAR(12), RLS_ORDR_MOD_TXT VARCHAR(255) ) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS TEXTFILE location '/hdfs/data-lake/master/criminal/csv/ccce_apl'; Thanks.

I just saw this thread after commenting on the Jira. Would "conv()" be a suitable workaround here? select conv('100010', 2, 10);

Fetched 1 row(s) in 0.24s More information on conv() can be found in the Impala documentation. Edit: To make things complete, the Jira is IMPALA-4968.
