AtlasClientV2#updateGlossaryByGuid method is used to update the glossary by guid.
Signature
public AtlasGlossary updateGlossaryByGuid(String glossaryGuid, AtlasGlossary updatedGlossary) throws AtlasServiceException
Example
AtlasGlossary glossaryToUpdate = new AtlasGlossary();
glossaryToUpdate.setName(atlasGlossary.getName() + "_updated");
glossaryToUpdate.setShortDescription(atlasGlossary.getShortDescription() + "_updated");
atlasGlossary = atlasClient.updateGlossaryByGuid(glossaryId, glossaryToUpdate);
Before updating the glossary ‘myGlosary3’
