 	_ = hc.AddTestTablet(cell, "e0-", 1, "TestExecutor", "e0-", topodatapb.TabletType_PRIMARY, true, 1, nil)

+	_ = hc.AddTestTablet(cell, "e0-", 1, "TestXBadVSchema", "-20", topodatapb.TabletType_PRIMARY, true, 1, nil)


the problem seems to be related to hostname, if you change the hostname from e0- to random the test starts working.
The bug may be a test thing when the hostname is the same.

ah good point. we should change e0- to -20 to match the shard name and make it unique.

-20 also conflicts. I guess we should make it 0.
I tried that, the next error is

--- FAIL: TestExecutorMaxPayloadSizeExceeded (0.00s) executor_test.go:1992: Error Trace: executor_test.go:1992 Error: Not equal: expected: <nil>(<nil>) actual : *vterrors.fundamental(Code: NOT_FOUND tablet aa-0000000010 not found ) Test: TestExecutorMaxPayloadSizeExceeded Messages: err should be nil

for failing test, the issue is due to a global session named primarySession getting used.
instead create a local session for those tests and use exec or executorExecSession instead of executorExec

What I did instead is to not initialize primarySession when it is declared, but create it in each of the test env functions - createExecutorEnv etc. That seems to fix all the failures in this particular test.

@deepthi in healthcheck.go you left a ToDo to deprecate some variables. I am not sure which ones you were talking about. Can you guide me?

Link to the corresponding ToDo:

Not deprecate, just change from exported -> not. All 6 flags below that comment should be reviewed to see if they are still being used outside discovery package. If not, we can change them back.
