zhangsong commented on KUDU-1551:
---------------------------------
[~tlipcon] for the workaround , in below code , pit_schema will be empty (has
no column id), if segments[0] is preallocated with no header written.
So what i need to do is delete this segment? Should i continue to rewind
pit_schema from segments[1]?
if (!segments.empty()) {
const scoped_refptr<ReadableLogSegment>& segment = segments[0];
// Set the point-in-time schema for the tablet based on the log header.
Schema pit_schema;
RETURN_NOT_OK_PREPEND(SchemaFromPB(segment->header().schema(), &pit_schema),
"Couldn't decode log segment schema");
RETURN_NOT_OK_PREPEND(tablet_->RewindSchemaForBootstrap(
pit_schema, segment->header().schema_version()),
"couldn't set point-in-time schema");
}
