When I install IBM Big Insights Quick Start Editor 3.0.0.0, other components are correct except the Big SQL component that has an error:

can not start the Big SQL Head Node and Big SQL Scheduler Nodes .

When I　run ./start.sh bigsql in <BIGINSIGHTS_HOME>/bin 

Starting Big SQL Scheduler     : FAIL
   ** Exception in thread "main" java.lang.NoClassDefFoundError: com.ibm.biginsights.bigsql.scheduler.server.SchedulerConfiguration

Get following error when in run ./bigsql start in <BIGINSIGHTS_HOME>/bigsql/bin

Have not find any tips in the official document ,but can fixed it by following :

run command :./bigsql-setup.sh in /opt/ibm/biginsights/bigsql/install

[bigsql@dpev210 install]$ ./bigsql-setup.sh
Logging output to: /bi/opt/ibm/biginsights/bigsql/install/bigsql-setup-140630105118.log

Setup is complete. Log file can be found at /bi/opt/ibm/biginsights/bigsql/install/bigsql-setup-140630105118.log.

after ran above command ,the Big SQL server will be up .

First try running the BigSql again by doing following commands: 1. Go to the folder : $HOME/opt/ibm/biginsights/bigsql/install 2. And then run the command : #./bigsql-setup.sh
The bigsql might get installed now, but I got the setup failed at creating database. The problem occurs for the following reasons: 1. The file permissions not set properly to create the database at particular location. 2. The mounting of the files is done.

For the file permissions: 1. Go to: /home/biadmin/var/ibm/biginsights/database/bigsql and change the permissions of the directory to 777 in all the blades by running the command.

chmod –R 777 bigsql

Again try running bigsql. Go to the folder: $HOME/opt/ibm/biginsights/bigsql/install And then run the command: #./bigsql-setup.sh
I got setup failed again, and appeared below: Creating Database Bigsql : Error

SQL1005N The database alias "BIGSQL" already exists in either the local database directory or system database directory.

then I tried running the below command logging as bigsql user:

db2 catalog DATABASE BIGSQL and reboot all the blades.

Again try running bigsql. Go to the folder: $HOME/opt/ibm/biginsights/bigsql/install And then run the command: #./bigsql-setup.sh
Now, I got the setup success and appear like below: [bigsql@dpev210 install]$ ./bigsql-setup.sh Logging output to: /bi/opt/ibm/biginsights/bigsql/install/bigsql-setup-140630105118.log

Setup is complete. Log file can be found at /bi/opt/ibm/biginsights/bigsql/install/bigsql-setup-140630105118.log.

Now, I started all the processes. Go to folder: $HOME/opt/ibm/biginsights/bin/ And running the command: # ./start-all.sh
as biadmin user. Now, checking the IBM console I got the bigsql running.

I was running into the same issue and then I tried your solution. But while I was trying your solution, the setup was not able to complete and was giving error at step.

Creating  Database Bigsql : Error

SQL1005N  The database alias "BIGSQL" already exists in either the local
database directory or system database directory.

I resolved it by cataloging the BIGSQL database using 

db2 catalog database BIGSQL

Link:http://www-01.ibm.com/support/knowledgecenter/SS3JRN_7.2.0/com.ibm.itcamsoa.doc/kd4trmst32.htm%23wq38

After cataloging it, it becomes available during bigsql-setup and succeeds.
