ramtin updated MAPREDUCE-6246: ------------------------------ Description: DBoutputformat is used for writing output of mapreduce jobs to the database and when used with db2 jdbc drivers it fails with following error com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601, SQLERRMC=;;,COUNT) VALUES (?,?);END-OF-STATEMENT, DRIVER=4.16.53 at com.ibm.db2.jcc.am.fd.a(fd.java:739) at com.ibm.db2.jcc.am.fd.a(fd.java:60) at com.ibm.db2.jcc.am.fd.a(fd.java:127) was: DBoutputformat is used for writing output of mapreduce jobs to the database and when used with db2 jdbc drivers it fails with following error com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601, SQLERRMC=;;,COUNT) VALUES (?,?);END-OF-STATEMENT, DRIVER=4.16.53 at com.ibm.db2.jcc.am.fd.a(fd.java:739) at com.ibm.db2.jcc.am.fd.a(fd.java:60) at com.ibm.db2.jcc.am.fd.a(fd.java:127) In DBOutputFormat class there is constructQuery method that generates "INSERT INTO" statement with semicolon(";") at the end. Semicolon is ANSI SQL-92 standard character for a statement terminator but this feature is disabled(OFF) as a default settings in IBM DB2. Although by using -t we can turn it ON for db2. (http://www-01.ibm.com/support/knowledgecenter/SSEPGG_9.7.0/com.ibm.db2.luw.admin.cmd.doc/doc/r0010410.html?cp=SSEPGG_9.7.0%2F3-6-2-0-2). But there are some products that already built on top of this default setting (OFF) so by turning ON this feature make them error prone. > DBOutputFormat.java appending extra semicolon to query which is incompatible > with DB2 > ------------------------------------------------------------------------------------- > > Key: MAPREDUCE-6246 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6246 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv1, mrv2 > Affects Versions: 2.4.1 > Environment: OS: RHEL 5.x, RHEL 6.x, SLES 11.x > Platform: xSeries, pSeries > Browser: Firefox, IE > Security Settings: No Security, Flat file, LDAP, PAM > File System: HDFS, GPFS FPO > Reporter: ramtin > Assignee: ramtin > Labels: DB2, mapreduce > Fix For: 2.4.1 > > Attachments: MAPREDUCE-6246.patch > > Original Estimate: 24h > Remaining Estimate: 24h > > DBoutputformat is used for writing output of mapreduce jobs to the database > and when used with db2 jdbc drivers it fails with following error > com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-104, > SQLSTATE=42601, SQLERRMC=;;,COUNT) VALUES (?,?);END-OF-STATEMENT, > DRIVER=4.16.53 at com.ibm.db2.jcc.am.fd.a(fd.java:739) at > com.ibm.db2.jcc.am.fd.a(fd.java:60) at com.ibm.db2.jcc.am.fd.a(fd.java:127) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
