-----------------------------------

             Summary: If multiple views are based on tables not defined in the yaml config file, dropping one of the views will throw exception
                 Key: FLINK-17045
                 URL: https://issues.apache.org/jira/browse/FLINK-17045
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Client
    Affects Versions: 1.11.0
            Reporter: Caizhi Weng


Add the following test in {{LocalExecutorITCase}} and run it
{code:java}
@Test
public void testBuggyViews() throws Exception {
    final Executor executor = createDefaultExecutor(clusterClient);
    final SessionContext session = new SessionContext("test-session", new Environment());
    String sessionId = executor.openSession(session);

    final String ddlTemplate = "create table %s(\n" +
        "  a int,\n" +
        "  b bigint,\n" +
        "  c varchar\n" +
        ") with (\n" +
        "  'connector.type'='filesystem',\n" +
        "  'format.type'='csv',\n" +
        "  'connector.path'='xxx'\n" +
        ")\n";

    executor.useCatalog(sessionId, "catalog1");
    executor.createTable(sessionId, String.format(ddlTemplate, "MyTable1"));
    executor.createTable(sessionId, String.format(ddlTemplate, "MyTable2"));

    executor.addView(sessionId, "AdditionalView1", "SELECT * FROM MyTable1");
    executor.addView(sessionId, "AdditionalView2", "SELECT * FROM MyTable2");

    // exception thrown here
    executor.removeView(sessionId, "AdditionalView1");

    executor.closeSession(sessionId);
}
{code}
The following exception is thrown
{code:java}

This is caused by not adding the {{SessionState}} in {{LocalExecutor#removeView}} when creating the new builder.
{code:java}
if (newEnv.getTables().remove(name) != null) {
   // Renew the ExecutionContext.
   this.contextMap.put(
         sessionId,
         createExecutionContextBuilder(context.getOriginalSessionContext())
               // should be: .env(newEnv).sessionState(getExecutionContext(sessionId).getSessionState()).build());
               .env(newEnv).build());
}{code}
