Error while creating hive table through Kylin build cube

Question

HI I am trying to build a cube with Kylin, the data gets souced fine from sqoop but the next step for creating hive tables fails . Looking at the command being fired it looks weird as the create statement looks good to me .

I think the issue is with DOUBLE types as when I remove the same the create statement works fine . Can someone please help .

I am using the stack in AWS EMR, kylin 2.5 hive 2.3.0

The errors logs with commands as as below

Command

    hive -e "USE default;
DROP TABLE IF EXISTS kylin_intermediate_fm_inv_holdings_8a1c33df_d12b_3609_13ee_39e169169368;

Answer 1

I installed the newest stable hive in my test env, which version is 2.3.4( Hive DDL doc says 2.2.0 support double with precision). I found hive didn't not support double with specific/user-defined precision.

e.g.

• [ERROR] create table haha(ha double 10);
• [ERROR] create table haha(ha double Precision 17);
• [ERROR] create table haha(ha double(22));
• [CORRECT] create table haha(ha double Precision);

Hive CMD:

hive> use ss;
OK
Time taken: 0.015 seconds
hive> create table haha(ha double 10);
FAILED: ParseException line 1:28 extraneous input '10' expecting ) near '<EOF>'
hive> create table haha(ha double Precision 17);
FAILED: ParseException line 1:38 extraneous input '17' expecting ) near '<EOF>'
hive> create table haha(ha double(22));

So, as far as I can concerned, Hive didn't support such data type definition. It can not be resolved by kylin dev.

If you found any mistake, please let me know. And I found below links which maybe helpful:

1. https://cwiki.apache.org/confluence/display/hive/LanguageManual+DDL#LanguageManualDDL-CreateTableCreate/Drop/TruncateTable

2. https://issues.apache.org/jira/browse/HIVE-13556

Answer 2

Ohh I think I finally Figured it out seems DOUBLE with precision is not supported by Hive . But I think Kylin should take care of this while importing the jdbc metadata into the model .

Will raise an enhancement or bug in Kylin for the same .
