On Linux systems where SCIM (Smart Common Input Method) utility is enabled, the Content Assist feature of InfoSphere BigInsights Text Analytics Eclipse tool (pressing Ctrl + Space) will not work as expected.
When SCIM (Smart Common Input Method) utility is enabled on Linux systems, the Ctrl + Space key sequence is mapped to trigger some event of the SCIM utility. As this conflicts with the key binding for invoking Content Assist feature of InfoSphere BigInsights Text Analytics Eclipse Tool, the Content Assist feature stops working.
Linux systems with the SCIM utility enabled.
Resolving the problem
To make the Content Assist feature work on Linux systems with the SCIM utility, turn the SCIM utility off or configure a different keyboard shortcut for the SCIM utility.
