Sergey Soldatov commented on PHOENIX-2783: ------------------------------------------ [~jamestaylor] Interesting. How {{SELECT i FROM tbl1}} is supposed to work in this case? I understand that from HBase point of view it's a valid case, but what about the SQL. And we already have quite unpredictable behavior in this case: {noformat} 0: jdbc:phoenix:localhost> create table tbl (id integer primary key, id integer); No rows affected (1.278 seconds) 0: jdbc:phoenix:localhost> upsert into tbl values (1,2); 1 row affected (0.041 seconds) 0: jdbc:phoenix:localhost> select * from tbl; +-----+-----+ | ID | ID | +-----+-----+ | 1 | 1 | +-----+-----+ 1 row selected (0.026 seconds) {noformat} > Creating secondary index with duplicated columns makes the catalog corrupted > ---------------------------------------------------------------------------- > > Key: PHOENIX-2783 > URL: https://issues.apache.org/jira/browse/PHOENIX-2783 > Project: Phoenix > Issue Type: Bug > Affects Versions: 4.7.0 > Reporter: Sergey Soldatov > Assignee: Sergey Soldatov > Attachments: PHOENIX-2783-1.patch, PHOENIX-2783-2.patch, > PHOENIX-2783-3.patch, PHOENIX-2783-4.patch, PHOENIX-2783-INIT.patch > > > Simple example > {noformat} > create table x (t1 varchar primary key, t2 varchar, t3 varchar); > create index idx on x (t2) include (t1,t3,t3); > {noformat} > cause an exception that duplicated column was detected, but the client > updates the catalog before throwing it and makes it unusable. All following > attempt to use table x cause an exception ArrayIndexOutOfBounds. This problem > was discussed on the user list recently. > The cause of the problem is that check for duplicated columns happen in > PTableImpl after MetaDataClient complete the server createTable. > The simple way to fix is to add a similar check in MetaDataClient before > createTable is called. > Possible someone can suggest a more elegant way to fix it? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
