mapping hbase to phoenix tables going wrong

aliyesami — Mon, 16 Apr 2018 22:47:00 GMT

i have read all the posts regarding this but still I am not able to get it right 😞

see blow the first query is showing a new column with name "PK" and ACCT_NUM empty .

the second query showing ACCT_NUM empty and PUR_ID populated.

how can I map all the columns of a column family to the phoenix table columns where the hbase row key becomes the primary key column of the phoenix table ?

hbase(main):001:0> scan 'PUR_ACCT_PHX2',{FILTER=>"(PrefixFilter('1001181'))"}

hi Josh I did follow that link but its showing one column table example and I have multiple columns , I tried various options to make multiple columns to work but I am not able to , kindly advise

another post I found on this forum is suggesting exactly the same way I am trying to create the table so what I am doing wrong?

The commands you shared in your initial question are not what that post says to do for a Phoenix table mapped to an HBase table. You said you ran `CREATE TABLE`, but that FAQ instructs you to use `CREATE VIEW`.

ok thanks Josh I figured out my mistake . I didn't realize that phoenix automatically find the primary key and I don't have to specify the primary key column name explicitly .

thanks for the guidance .
