Failed to map keys for cache (all partition nodes left the grid)

Hi, I'm seeing the errors below in my ignite cluster. This occurs consistently in my env when I apply a "rolling upgrade" where I take down one node at a time by updating them with a new jar file then start it up. Once the node is up I then apply this to the next node and so on. Notes: The

Re: Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near ','

That column with the : is also an issue but in SQL server you can either quote columns in quotes or square braces. I would have expected Ignite to generate code with quoted columns because even a simple space in the name is a problem in the current statement regardless of the column with : in it.

i think i found the issue it is related to the select not quoting columns. I ran a trace against the database and executed each query generated separately. Is this a driver issue or an ignite issue? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
