Description

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, the table is a msql table which had columns with DOUBLE type

Command

hive -e "USE default; DROP TABLE IF EXISTS kylin_intermediate_fm_inv_holdings_8a1c33df_d12b_3609_13ee_39e169169368; CREATE EXTERNAL TABLE IF NOT EXISTS kylin_intermediate_fm_inv_holdings_8a1c33df_d12b_3609_13ee_39e169169368 ( HOLDINGS_STOCK_INVESTOR_ID string ,STOCK_INVESTORS_CHANNEL string ,STOCK_STOCK_ID string ,STOCK_DOMICILE string ,STOCK_STOCK_NM string ,STOCK_APPROACH string ,STOCK_STOCK_TYP string ,INVESTOR_ID string ,INVESTOR_NM string ,INVESTOR_DOMICILE_CNTRY string ,CLIENT_NM string ,INVESTOR_HOLDINGS_GROSS_ASSETS_USD double(22) ,INVESTOR_HOLDINGS_NET_ASSETS_USD double(22) ) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 's3://wfg1tst-models/kylin/kylin_metadata/kylin-4ae3b18b-831b-da66-eb8c-7318245c4448/kylin_intermediate_fm_inv_holdings_8a1c33df_d12b_3609_13ee_39e169169368'; ALTER TABLE kylin_intermediate_fm_inv_holdings_8a1c33df_d12b_3609_13ee_39e169169368 SET TBLPROPERTIES('auto.purge'='true'); " --hiveconf hive.merge.mapredfiles=false --hiveconf hive.auto.convert.join=true --hiveconf dfs.replication=2 --hiveconf hive.exec.compress.output=true --hiveconf hive.auto.convert.join.noconditionaltask=true --hiveconf mapreduce.job.split.metainfo.maxsize=-1 --hiveconf hive.merge.mapfiles=false --hiveconf hive.auto.convert.join.noconditionaltask.size=100000000 --hiveconf hive.stats.autogather=true

More details here  https://stackoverflow.com/questions/53377623/error-while-creating-hive-table-through-kylin-build-cube . Though the same got solved when I used DECIMAL type with precision .

 

Also observer that if you use DECIMAL(10) it does not work unless it has a precision while building mode for the same it gives error as tries to use precision as undefined ie . DECIMAL(10,undefined)
